Harry Potter and the Deathly Hallows, the final volume in the Harry Potter series is one of the most anticipated books of the upcoming year. Author J.K. Rowling has just announced the official publication date, which is July 21, 2007.
Ms. Rowling has already suggested that there will be at least one death in Book 7, and there are many issues and questions that still need to be answered. At Borders, we're especially curious about one character, sure to play a central role in Harry's final year at Hogwarts.
Severus Snape: Friend or Foe?
Snape is a powerful and gifted wizard who possesses a ruthless and cunning wit, is rarely caught off guard by any comment or insult and often leaves his verbal combatants with little to say. His allegiances are a mystery however. Is he loyal to Dumbledore and a friend to Harry Potter? Or is Snape loyal to Voldemort, and a foe of Harry Potter?
Here's some questions we have about Snape
Snape is a Friend
1. In Harry Potter and the Sorcerer’s Stone, why did Snape attempt to protect Harry from Professor Quirrell?
2. Why didn’t Snape go to the graveyard immediately upon being summoned by Voldemort in Harry Potter and the Goblet of Fire?
3. In Harry Potter and the Order of the Phoenix, why did Snape alert the Order of the Phoenix that Harry was facing danger at the ministry?
4. In Harry Potter and the Order of the Phoenix, why did Snape agree to teach Harry Occumency?
5. Dumbledore tells Harry he trusts Snape in Harry Potter and the Order of the Phoenix and again it is implied in Harry Potter and the Half Blood Prince. Would Dumbledore, the most powerful wizard of his time, misplace his trust in Snape?
6. Why does Snape spare Harry’s life in Harry Potter and the Half Blood Prince?
Snape is a Foe
1. Beginning with Harry Potter and the Sorcerer's Stone, Snape displays a dislike of Harry. Is a childhood grudge against his father reason enough to hate Harry or is it something more?
2. Why was Snape so set on expelling Harry from Hogwarts in Harry Potter and the Chamber of Secrets?
3. In Harry Potter and the Goblet of Fire, what were Snape and Karkaroff conspiring about?
4. Knowing the danger Harry faced, why did Snape continue to goad Sirius in Harry Potter and the Order of the Phoenix?
5. In Harry Potter and the Half Blood Prince, what were Snape’s motives for his Unbreakable Vow with Narcissa?
6. And of course, there is the major question of Snape and Dumbledore in Harry Potter and the Half Blood Prince. We'll leave out the details for anyone that may not have yet read the books.
What do you think? Friend or foe?

Unlike Danielle T. I don't think Harry's parents asked Snape to watch over him. I think Snape has because he is a good person. Snape was jealous of Potter's parents - yes... but I don't think that is the whole reason he is so strict with Harry. I think that Snape is strict with Harry because he wants Harry to do better - to do well in life. It's like the teachers you may have had in school who seemed to single you out to pick on you. But in the end you realize they see potential in you and are just pushing you to excel.
I'm anxious to see how everything turns out.
(I do wish Minerva McGonigle[sp?] was a stronger character...)
Oh, no... as the series ends, how can I say that!?
I am still torn on this issue. I agree with Angela about Dumbledore coming back (ala Gandolf in "Lord of the Rings") but also think perhaps he's not even dead. The whole 5th and 6th books are about silent incantations - perhaps Snape said a DIFFERENT incantation in his head and he and Dumbledore are the only ones who know he is still alive? I know, it's a stretch, but in all the other books, when someone gets hit with that curse, they just drop - why did Dumbledore go flying off the tower?
I think he made the Unbreakable Vow because if he hadn't, they would have known he was a traitor. Perhaps he made it and told Dumbledore, and together they agreed that if it came down to it, Snape had to kill him to protect his role as spy with Voldemort (as other comments suggest).
I am curious as to why Dumbledore never told Harry his reasons for trusting Snape. Perhaps we will find out in the next book?
There are so many characters in the story who want to help Harry, but hardly any who would actually be of any use in a battle with Voldemort. Neville Longbottom is one of those few, I think, and I expect he's going to have a very large role in the final conflict. Other than Neville, the only other character who might reasonably be involved with the final battle and who is also strong enough to impact the course of it is Snape. While Voldemort is focused on Harry, Snape can strike by surprise. Even if he doesn't kill Voldemort, chances are good he'll either wound him or distract him long enough for Harry to kill him.
It could be that Harry & Voldemort can't kill each other; if that's the case, someone else will have to kill Voldemort. Snape would be perfect for the job, and he's expendable.
I think Snape is a Slytherin through and through. He will a line himself with anyone, and everyone in power, and he is a double agent working for himself.
His occumency skills are excellent, and I think he is powerful enough to give both Dumbledore and Voldemort any impression that will befit him in the end.
In the Sorcerer's Stone Snape dislikes Harry because he represents the conflict in his life, trying to appear on both sides at once. He helps potter because if he can keep the dark lord away, in a subtle way, (keeping Potter alive) no one will notice any true alliance. He can safely continue to play both sides, but with less effort then would be required if Voldemort returned.
In the chamber of secrets book Snape wants potter expelled because with out him near by, less can be asked on him.
In the fire goblet Snape does not go to the graveyard because it is a power trip to manipulate both sides.
In the order of the phoenix Snape teaches potter occumency because it is asked of him. It unclear weather or not Snape was helping the dark lord to get into Potter's mind, or to help the potter rebuff him. Dumbledore believes Snape will be loyal to the power of the winning side. It is not so much that he trusts Snape, but that he knows how to play him in a given situation.
In half blood prince Snape could not have asked for a better fall back to confuse both sides to his loyalty then the unbreakable vowel. He must take it form Dumbledore side to avoid arousing suspicion, and from the other to cement family ties, and avoid showing weakness. In the end of the book he acts for himself, if he does not do what is promised, then he will die. He acts with crowdedness to save his own neck, but does not kill Potter, because that act of kindness allows him to able to talk his way back to that team.
In the end, Snape will be position himself on the winning side to soak up as much power and glory as possible. Will that side take notice of his inconsistent actions, and accuse him of treason? Of course not, he has played his cards too well. At the end of the story his will be is a Slytherin through and through, and he will have gone to any means to achieve his end.
Snape seems like a true Machiavelle. Though if I were looking to predict his actions and out comes I would look for him to step up his display of power at some crucial time somewhere near the middle of the next book, having concealed some bit of his real capability, and disposing of voldimort (or perhaps just using his position to catch the villain at a weak moment). From there I think harry will have to battle Snape in a final showdon to gain his ends for good.
That's just how it looks to an outsider.
Starting with the death, Dumbledore knew the only way he could save a student - Malfoy - was to die. He has shown that he would rather risk it all than have harm come to one of his students. He communicated as much to Snape, who is a skilled Legilimens.
(I for one believe he is truly dead. Too often have we heard that "Harry is safe as long as Dumbledore's alive." There are no stakes in the final battle with Dumbledore in the picture.)
But Snape could have murdered Harry any number of times, lured him into danger, sold him out. And Snape's rage at being called a coward when he had just killed the only man who ever understood him was immense.
I don't think he likes Harry. I think he hates him. But Dumbledore once said that when a wizard saves another wizards life, there is a bond, an obligation between them. Harry's dad saved Snape, and Snape was unable to repay the favor, so he is endebted to the son. It drives him mad that this is true, he loathes it, but it's a fact - he owes Harry a debt. So - a reluctant friend.
On the other hand, I think a part of him is still drawn to Voldemort and he fights it and sometimes gives in to the urge. I think he's fighting his own battle inside, and therefore decides when it suits him whether he will be friend or foe.
Snape had no real choice in the matter, everyone knows that Malfoy is a coward, he would never be able to kill anyone. If Snape hadn't than the deatheaters would have killed Dumbledore and Malfoy both, which would have killed Snape and no one would be left to tell the truth or continue on. With no one there to protect Harry Potter the deatheaters would have turned on him and killed him too.
As far as Dumbledore coming back in Book 7, I don't think so. In my mind that is cheating and an easy way out, that isn't her style. Remember on page 626 of the American hardcover edition, "And a new portrait had joined the ranks of the dead headmasters and headmistresses of Hogwarts." Sorry people he is dead and he's not coming back, remember what Dumbledore had said about coming back, there's no honest way to do it and being a ghost meant for Dumbledore that he would have had some sort of unresolved issue and he never really regretted any decisions he made, none that would keep him on Earth anyway, I believe he said as much to Harry about that.
Dumbledore pleaded with Severus in the moments before his death. But it is not said in the book what he is pleading for. I believe Dumbledore was actually asking Severus to kill him before Draco could, to protect Draco from the evil of killing another human being.
The hate needed in order to cast the Avada Kedavra spell came from Snape's own hate of himself for what he had to do. Hence, Snape's anger as Harry chased him, yelling that he was a coward. He had just done something he never imagined he'd actually do and for Harry to call him a coward was a great insult when he had done what was asked of him by Dumbledore.
My boyfriend on the otherhand, believes Snape is neither good nor bad. He is just out for himself, making sure he will survive the battle until the end.
And, as an aside to the aside, I hope Sirius will be back - Harry needs him and as a character he was never completely fleshed out. Coming back from the dead is, as someone mentioned, a cheat and beneath the talented Ms. Rowling -- but I'd still love to see him again!
I think Harry will be intent on killing Severus, but in the end they will unite and do battle with the dark lord. I think it would take someone with Snape's abililities and help from someone like Harry with his ties to the dark lord in order to kill Voldemort.
The real question is, what will happen to Harry so J.K. doesn't have to write more books, will he lose his power? Or will he end up in the hospital with his former defense of the dark arts teacher and Neville's parents?
1. Beginning with Harry Potter and the Sorcerer's Stone, Snape displays a dislike of Harry. Is a childhood grudge against his father reason enough to hate Harry or is it something more?
Not only does Snape hold a childhood grudge against Harry's father, he holds a grudge against his mother, his godfather, and his father's other best friend (which is all revealed in Harry Potter and the Prisoner of Azkaban and Harry Potter and the Order of the Phoenix). He disliked James Potter and Sirius Black because they were the most popular guys in school, Remus Lupin because he was their friend, and Lily Potter because she was a Muggle-born witch. Remember, the Slytherins prided themselves on being purebloods, and surely someone who was teased and taunted and driven to be a Death Eater such as Severus Snape was no exception. In addition, remember that Harry bears a striking resemblance to his father, so every time Snape looks at him, it's the past being resurrected. If you're the most loyal of Voldemort's followers and you're the ultimate spy, then being what amounts to little more than a living ghost of the past would make it very easy for Snape to hate a child that had nothing to do with the wrongs done to him. It may not be right, but it is understandable.
2. Why was Snape so set on expelling Harry from Hogwarts in Harry Potter and the Chamber of Secrets?
Snape was so set on expelling Harry from Hogwarts in Harry Potter and the Chamber of Secrets because short of Voldemort being resurrected in Harry Potter and the Goblet of Fire, this was the best possible chance for anyone to get rid of him. If he were expelled from Hogwarts in his second year, Harry would not have enough skill to control the magic that flowed within him which amounts basically to leaving him defenseless against an attack from a Death Eater like Lucius Malfoy or his goons.
3. In Harry Potter and the Goblet of Fire, what were Snape and Karkaroff conspiring about?
Snape and Karkaroff are not necessarily conspiring; Snape is aware of what is going on around him and knows that eyes are constantly watching him. Karkaroff, on the other hand, knows that he sold out a lot of Death Eaters to gain his own freedom and sees Snape as a potential ally. Not many people know or remember that Snape was also a Death Eater, but Karkaroff, being the true coward, sees the signs of Voldemort's imminent return and tries in vain to gain Snape's assistance. Like Sirius says to Harry in the fireplace, "No one stops being a Death Eater."
4. Knowing the danger Harry faced, why did Snape continue to goad Sirius in Harry Potter and the Order of the Phoenix?
Like Dumbledore said after Sirius's death, some wounds just go too deep for the healing. Sirius and Snape were childhood enemies. Sirius also came from one of the oldest and richest pureblood wizarding families in existence at the time, whereas Snape was just a half-blood that came from the wrong side of the tracks. Based on the glimpses that Harry got of Snape's memories during the abortive Occlumency lessons, it would appear that Snape came from an abusive home that lacked for a lot of creature comforts. Because Sirius and Snape were the childhood enemies that continued to fight long after childhood passed, and because Sirius was still a fugitive from justice, Snape saw it as an opportunity to get back at him for all the wrongs done to him in school, in addition to vent his spleen at the ghost of James Potter, who he always felt treated him the worst of all because Sirius was his best friend.
5. In Harry Potter and the Half Blood Prince, what were Snape's motives for his Unbreakable Vow with Narcissa?
Snape's motives was simple -- as a double agent, he had to make sure the plan was carried out to kill Dumbledore. He knew the time was coming, but he also knew that Draco Malfoy was not capable of carrying out the task. In order to calm a hysterical mother and shut up a cynical sister, he made the Unbreakable Vow. Bellatrix Lestrange, insane though she was, insisted that she was the closest to Voldemort; however, only one who was privy to his most secret plans would be able to make that Unbreakable Vow so calmly knowing the consequences. That also showed Bellatrix and Narcissa, who could tell anyone else who asked, that Severus Snape was indeed very high up on the chain of command in Voldemort's inner circle and therefore not to be crossed.
6. And of course, there is the major question of Snape and Dumbledore in Harry Potter and the Half Blood Prince. We'll leave out the details for anyone that may not have yet read the books.
This is simple -- he completed the job that Draco Malfoy could not do and that Dumbledore expected him to do. I believe that Dumbledore is indeed dead, but at the same time I also believe that another character who has been mentioned -- Regullus Black -- is going to come into play with these two characters in a way that nobody expects. I say this because the note that came with the fake Horcrux is signed with the initials RAB, which also happens to be Sirius's brother's initials, and Sirius's brother was also personally killed by Voldemort (we know this because Harry is told this by Sirius in Harry Potter and the Order of the Phoenix, although Sirius expresses his skepticism about it.) In the end, Snape is not so much a foe as he is an antihero, which is neither friend nor foe, but Snape, even though he is the Half-Blood Prince, is not going to be the one who is the central character in this little drama as the Harry Potter Saga reaches its conclusion.
J.K. Rowling has written an excellent series that can be read on multiple levels; too bad this one has to end, but then again, all great series do at some point!
snape is the type of person that would rather come up and help out of no where rather than straight out say he is a good guy. i think he is scheming something in harry's favor, something even dumbledore might not have even been aware of. yes he commited murder but he had no choice or would have blown his cover and would have died.
Snape is a Schemer ill leave it at that but i still say friend.
man i cant wait for the next book. !!!!!!
The jealousy Snape toward Harry is what makes him seem unwilling to help Harry at times. In the end it will become apparent that his act toward Dumbledore in "The Half Blood Prince" was for the greater good of the Order. Dumbledore trusts snape and I believe he has impecable judgement. Dumbledore is not gone for good, come on, he can't be. Good prevails though Ron, Hermione or Harry dies to make it happen.
Also, because of his ties to Lucius he is obligated to mentor Draco (who, incidentally, will also become a "friend" because he is Harry's lover). :D
2. Why was Snape so set on expelling Harry from Hogwarts in Harry Potter and the Chamber of Secrets?
Well, if you were on Dumbledore's side but Voldemort and his minions thought you were on theirs, you'd do everything you could to make it seem that you're set against Harry and Dumbledore. He's just making it seem like he's doing what he can without being blatantly evil against Dumbledore (so Dumbledore thinks his dislike of Harry is more towards the blatant hate of James), and still seem like he's making attempts to help out Voldemort.
3. In Harry Potter and the Goblet of Fire, what were Snape and Karkaroff conspiring about?
If you recall, neither one of them returned to Voldemort when he called for them in the graveyard. They both felt the call, but both of them knew that, for different reasons, they couldn't return. Especially since the Dark Lord seems to have numerous ways of getting a scrap of information out of them. Maybe they were aware that they wouldn't have been able to hide their secrets from him. Karkaroff is just more jumpy than Snape, so he must have freaked a little bit and talked to Snape to see what he was up to.
(I would put more, but I have to go to school now.)
"Harry and Dumbledore are up on the top of the tower underneath the Dark Mark. Harry is wearing his invisibility cloak, Dumbledore ordered him to put it on before they mounted their brooms to ride to the top of the tower. Harry hears footsteps and looks around, but Dumbledore orders him with a gesture to retreat. Harry draws his wand and backs away:
The door burst open and somebody erupted through it and shouted, "Expelliarmus!" Harry's body became instantly rigid and immobile, and he felt himself fall back against the tower wall, propped like an unsteady statue, unable to move or speak.(HBP pg 584/545)
It's interesting to note that things are happening so fast, even Harry is momentarily confused:
He could not understand how it happened -- Expelliarmus was not a Freezing Charm -- Then, by the light of the Mark, he saw Dumbledore's wand flying in an arc over the edge of the ramparts and understood... Dumbledore had wordlessly immobilzed Harry, and the second he had taken to perform this spell had cost him the chance of defending himself. (HBP pg 584/545)
Why did Dumbledore freeze Harry? Harry was already invisible to their attackers and in no danger.
The only explanation could be that Dumbledore already knew, had already planned, that he would die this night (or appear to die), and not only did he not want Harry to become involved and possibly be injured himself, he needed Harry to be a witness, to be able to tell everyone else what happened.
Dumbledore might have also promised Snape that he would make sure that Harry would not be able to interfere, knowing how Harry feels about Snape and what Snape was about to have to do.
The supposition that it was Dumbledore's plan to do this all along is supported by the fact that he acted so quickly to do it, almost without thinking, when Draco burst in on the scene.
Harry's own assumption that the Freezing Charm was done by Dumbledore is supported by the fact the curse lifted when Dumbledore left the tower minutes later."
There are more clues on the website. After reading all of them, I agree with them, when saying, "Dumbledore is either not dead or Snape's not a Death Eater and he killed Dumbledore because Dumbledore ordered him to"
As for Snape, I don't care for him much, but I think that he must have done something to prove himself to Dumbledore. I believe that he had to make the unbreakable vow with Narcissa so that he could feel important, knowing that he is privy to information only a few of Voldemorts followers knew. I think that the only reason he killed Dumbledore in the end was to save his own neck. Snape knew that Malfoy could not do it and so he had to or he too would die because of the unbreakable vow.
Also, I believe it said that the unbreakable vow was only made between dark wizards so for the person that said Snape and Dumbledore made an unbreakable vow, that is not possible. Dumbledore would not make a vow that would cost someone their life, he had other ways of keeping things secrect, just like he did with the Order of the Pheonix. Some of you should really go back and re-read some of the books. It is amazing what little things you miss the first time you read them.
I think that RAB is Regulus Black, and that the real locket horcrux is the locket that they found while they were cleaning out the drawing room in the Black house in the Order of the Pheonix. Regulus found it and brought it back to the Black house after he betrayed Voldemort (he was one of Voldemorts higher ups so he knew the location of the locket) They were not able to open the locket that they found in the Black house. Kreacher has probably hidden it in his little cubby hole by now!
Could Snape be Harry's Uncle? Could Snape detest his famous nephew?
Really think about it.
Could Snape be related to Dumbledor?
HMMMMMM.
1: It is obvious that Snape hates Harry. No denying that. He wants him expelled, he wants him failed, etc. Still, he doesn't want him dead.
2: Snape hates Harry for several reason, only a couple of which are obvious - Harry is James' son, everyone tells him how much he resembles him. Harry also has his mothers eyes, another thing everyone remarks on (both of these points are mentioned in every book). It will come out that Snape was in love with Lily Potter, yet another reason he hated James, and now Harry. He only has to look at Harry to be reminded of James.
3: Snapes love for Lily is what drove him to Dumbledore in the first place. He *was* a loyal Death Eater, but couldn't bring himself to help kill Lily. It is mentioned that he was a spy for Dumbledore, and that Dumbledore was given inside information that Voldemort was planning to kill the Potters.
So, is he a Friend or Foe? Well, both. He has a fascination, maybe even a love for the Dark Arts, but I think he's more like the avid gun collector that insist on having as many guns as possible and knowing how to use them very well. While he may not hesitate to use them in certain situations, he is almost certainly not going to use them just for fun. But he will use them. He certainly hates Harry, but his love for Lily won't let him harm Harry, or allow him to be harmed. He will play a big part in Harry's favor in the last book.
Dumbledore IS DEAD. He is NOT a christ figure. There is nothing to be gained by his return at this point, except a blatant ruination of an extremely compelling and fascinating story. Rowling is far too good a storyteller to pull such a blatant cheat. That would be worse than rewriting the "over the cliff" scene in an old western so that the hero obviously gets out, when the end of last weeks episode clearly showed him going over with the coach.
Besides, he states quite clearly in the first book that "To the well organized mind, Death is but the next great adventure". He's not afraid of death, and won't hang around as a ghost. Nearly Headless Nick spoke of his fear of "crossing over" as a grave regret he had after Sirius died, so I would bet money Dumbledore will NOT return, except through his portrait in the Headmistress' office, and through various memories that will surface in various forms.
Snape was forced to kill Dumbledore, and that will probably torture him (Snape) as much as Lilys death. If not more. He took the vow because he had to. He clearly didn't know what Dracos task was - Harry overheard Snape trying to drag it out of him well after the vow was taken. When he found out, moments before killing Dumbledore, he was certainly able to communicate with Dumbledore through Legilimency. Dumbledore was a very good legilimens too, as he mentions to Harry in HBP. He made it very clear to Snape that he was to carry on with the plan, even if it meant killing him. On the one hand, he was bound by the vow, on the other, he was bound by his word to Dumbledore, and the need to maintain his cover. Besides, as has been mentioned, Dumbledore probably had an idea what Dracos task was well before that night - he probably avoided telling Snape so Snape wouldn't have time to torture himself over it. I don't know if Snape and Dumbledore had an unbreakable vow, but it's possible. Dumbledore doesn't strike me as the kind to put another person under that kind of obligation. Still, that might have been the reason for his unswerving trust of Snape. Maybe Snape insisted on the vow?
So, it looks more like Snape is the tragic figure of the story. He's the one everyone loves to hate until his true motives are revealed. Of course, by then it will be too late. Snape has used an unforgivable curse, on one of the most respected and prominent wizards of modern times. No way he'll be allowed to go free. Not that he'll be able to live with himself anyway.
I suspect Karkaroff is already dead. Voldemort would have taken care of him for putting so many of the Death Eaters in Azkaban. As mentioned above, yes, he's "just a weenie". He's just another wormtail with a little Slavic style and less of the groveling gene.
In TDH, look for more of Sectus Sempra, the "up by the ankle" charm, and Harry learning silent spells and Occlumency. Possibly even some Legilimency (with a little help from the scar). The real question is where are the other Horcruxes? The locket fetched from the cave will turn out to have been removed by Sirius' brother Regulus, but he hasn't destroyed it. It's mentioned very briefly, more as an aside in The Order of the Phoenix - the locket nobody could open that was found while cleaning Sirius' house. The Ring and Book have been destroyed, by Dumbledore and Harry, leaving as many as 5. They think the locket is destroyed, and they think there were only 6 altogether. There has been speculation that Harry (or Harry's scar) is the last one, but I doubt that. There's still Nagini, possibly the Hufflepuff teacup, and one other object (maybe 2) that nobody has a clue to yet. I wouldn't be surprised if Snape has already destroyed one, or winds up destroying one in book 7 - maybe Nagini?
L
Without Dumbledore, Harry now must be able to survive on his own, without Dumbledore's guidance, protection, or foresight. He must now learn to think and fight for himself, and grow up into the independent wizard that Dumbledore has always wanted him to be.
With Snape, I am most certain that he was forced to kill Dumbledore, and not without regret, either. After all, I distinctly remember that passage, where he is about to kill Dumbledore, that his face was filled with hatred. Why this hatred? Surely he doesn't personally hate Dumbledore? Dumbledore is his enemy yes, but this personal hatred makes my skeptical, and my explanation for it would be thus: His loyalty towards Dumbledore makes him loathe the fact that he must be forced to execute him.
Furthermore, the last words that Dumbledore ever speaks are like this: "Severus, please, please." He is clearly begging Severus to do something, of course. But seeing what Dumbledore has given us from the previous five books, do we really QUESTION DUMBLEDORE'S COURAGE? He would not be the person to beg for mercy, particularly under such circumstances. Perhaps the other Death Eaters fail to notice this, and merely interpret this as a final hope for mercy, in a cowardly show of grovelling, but I am most sure that instead of pleading for life, that he was, in all actuality, pleading for HIS OWN DEATH. He sees the reluctance in Snape's eyes, and pleads for Snape to finish it.
He has a plan, you see, and Snape must be included in it. He begs for Snape to keep on with the plan. With this act, a few things are achieved, although I can imagine that Dumbledore knows the Dark Lord will have glazed over these things:
1) With Dumbledore gone, the Dark Lord will believe that he is now unstoppable, and will be overcome with intoxicating hubris and arrogance. The Dark Lord now believes himself to be invincible and unstoppable. He will, as a result, make some sort of stupid mistake by underestimating someone.
2) Harry will now become even more furious at all that is evil with the world (aka You-Know-Who/Voldemort/Voldy-thingy/The Dark Lord & his Death Eaters), and will resolve to defeat him with more determination than ever before. Now, the situation turns from a game of survival to a battle for victory. In short, Harry will be psyched up and mad.
3) Snape now has Voldemort's trust from this act. Snape will now become his greatest weakness, being that Voldemort has little, he thinks, to fear from Snape. Loyalty is a very useful tool for gaining trust.
All this will lead to Voldemort's downfall.
What I've written all this junk for is to say: Snape is good.
One, I do not believe Dumbledore ever misplaced his trust. In anyone.
Two, the only reason Snape gave the Unbreakable vow was to save Draco and Narcissa, both of whom he cares about deeply. He had no idea the vow would lead him to kill Dumbledore.
Three, despite Harry being James' son, he was also Lily's. Snape loved Lily. Harry may be a lot like his father, but he is also a lot like his mother. Whose idea was it to go and save Hermione first year? Who stands up for Neville also in the first year? Let's face it. Harry is his mother's son. The same traits that made Snape love Lily are reflected in the son of his worst enemy. Snape, for Lily's sake, would not turn his back on Harry or Dumbledore.
Four, c'mon, people! Snape is a double agent! He has to do some things in order to maintain his status. Killing Dumbledore does that, as well as protecting his favorite student.
In the last book, I believe that Harry will learn that everything is not as it seems and he must make up his own mind about everyone/everything. And grow up in the process.
Wouldn't it be kewl if Harry is really a death eater and they're just saying that Voldy is after Harry to make everyone think that Harry is the good guy so he can manipulate all his friends and stuffs? :D
I could go on and on about my conclusions on Snape but I'm just going to say what I believe will happen in the final book and let the book speak for itself.
I believe that both GOOD and EVIL; Lupin and Snape will play ONE among many Very important roles.
Ultimatly I expect SNAPE as well as LUPIN will SACRIFICE themselves to help Harry in his battle against Voldemort.
Agree or Disagree with me, either way this is my own conclusion on one of many questions I hope to be answered in the final book.
Furthermore, Dumbledore isn't dead. Unbeknownst to Snape, Dumbledore switched his wand with a prank wand from the Weasley brothers' joke shop. Ever wonder why nobody, Harry in particular, really SAW Dumbledore's body after he died? And his "body" was wrapped in a sheet?
Tammy brought up Sirius. If anyone came back he is the only likely one I can think of. We don't know that the veil he disappeared into was death. It could have been another thing like the wardrobe Draco used to bring the Death Eaters to the school.
As for Snape, I always thought he was a good guy with issues. Even when he took the Unbreakable Vow, he hesitated before saying the final words. Because of that, I don't think he wanted to do it. He knew how powerful it was and what it cost and didn't want to get involved, but if he didn't he would betray someone he cared about, no matter which side he was on. If he said no to the vow, Narcissa and Bellatrix would tell Voldemort that Snape was a traitor and he would die.
If he jumped right in without hesitation, he'd be a fool for not understanding the power of the Unbreakable Vow and they may also think he was sure Draco would fail, which would be a betrayal of Draco's own weakness. Saying that Draco was weak is totally against Snape's favoritism in class anyway.
Narcissa was worried because it was the first task Voldemort asked her son to do. She may also not want her son to be part of Voldemort's plan. It may be too late for Narcissa and Lucius to get out of Voldemort's clutches, or they think it is, but Draco might if he hasn't even really started yet. That certainly opens a can of worms.
I've seen a parallel between Snape's life and Harry's life in some instances. Could that be a clue? The Deathly Hallows will be huge! It has to be to answer all these questions!
