will Snape ever come to the good side?

I still believe Snape is a good man, even when he killed Dumbledore. If you'll remember, he made a promise that he couldn't break without dying. I have no doubt he told Dumbledore this, and, knowing Dumbledore's character, I have little doubt that Dumbledore requested that Snape kill him if it was necessary. That might explain what went on at the end of book 6. If I recall correctly, Snape was hesitant to kill Dumbledore, until Dumbledore started pleading with him. It could have been interpreted two ways:(1)Dumbledore was pleading for his life, or (2)Dumbledore was pleading for Snape to kill him and save himself. I guess will find out in the next book which one it was.

I hope he does. I don't want to think he was able to fool Dumbledore for all those years. I want to think it was all planned and the plan just didn't go right due to Dumbledore being too weak at that time due to the potion at the cave. Still we won't know for sure till the book comes out. Until then though I think we are all going to be wondering on it.

Here, I'll take a different route. I believe he's a mixture of good and bad. Switching to whichever will help him survive. If you read the first few chapters of the last book, he made an unbreakable vow. Which meant he HAD to do what he did, to protect Draco from getting murdered by Voldy. Snape's not exactly pure evil. But he's not exactly a saint either. He's what his life's made him, I think. Just look at his past, he was the mortal enemy of James Potter -- do you think if he had the choice, when picking sides, he'd want to be on the one with James? After all they'd done to eachother? He wasn't entirely well-liked . . seems like for his whole life. And being stuck with Voldy . . well as I said, he's what his life's made him. Stuck between two impossible choices. It'll be intresting to see what he does in the upcoming and final book.

I have some doubts as to Snape's loyalty to Dumbledore. If he has truly been working for the good side all along, how come he killed Dumbledore. I can't think of a reason that would be enough to justify this. If killing Dumbledore was somehow a plan to trick the dark lord into believing Snape's loyalties are with him, couldn't dumbledore and him concoct a better plan? one that doesn't actually kill Dumbledore? surely with him and dumbledore thinking together they could have done this. they were both very clever...

I don't think Snape has betrayed anyone, I think in the last book, his real intentions will be revealed and he is the one the saves everyone.

i'm, not sure what side snape was on that one fateful night in book 6, but if you recall, when snape was about to "do the deed" dumbledore started to show real fear in his voice-fear he didnt show with just malfoy before him. So I dont think, if snape was/is on the good side, it was in in the plan for dumbledore to..u know.., but instead a spur of the moment. My personal opinion is that snape was never on the good side, and that he's been with Voldemort the entire time, no matter how much dumbledore trusted him.
