Dumbledore is dead, snape used the killing spell and dumbledore's picture already appeard in the headmasters office (i think thats where it appeared), besides Harry was going to have to face Voldemort alone in this next book so she needed to kill off dumbledore.

Also with Harry being a Horcux i really think he is but alot of you got me thinking of how he might not be. If he isn't a Horcux i feel that the last one will be a person or animal just because i dont think that J.K Rowling would have said that a Horcux could be an animal for nothing

Snape was acting on Dumbledore's orders. I hope it is revealed in the next book why Dumbledore trusted Snape, I know it has to be more than he felt really bad.

That is why Hagrid overheard a convo between DD and Snape with Snape telling DD he's asking too much out of him. DD knew about the Unbreakable Vow with Malfoy and asked Snape to kill him if it comes down to it. Snape would then still be able to get more info on Voldermort and help Harry and also prevent Draco from killing anyone.


Even while Harry was chasing Snape in the end it seemed Snape was almost teaching him how to fight and held off Death Eaters wanting to attack Harry.

I'm sure something like this has been posted, but I think it is the only reasonable explanation for what happened, given all the clues in the book.
