Foe. Snape has already saved Harry once at the climax of the first book, it would be played for him to save Harry at the climax of the series. Dumbledore just made a mistake in trusting Snape. Snape is bad.
ok haha being serios. Its the peices of Voldemorts soul that harry or anyone has to destroy before they can kill voldemort. They destroyed the ring. The diary. And they think the snake is one. And the chain locket might have already been destroyed. AND probly hufflpuffs shit and something else
