I think he is evil.
Snape is definitely NOT evil... but I’m dying to find out what hold Dumbledore had over him to make him play out that scene in HBP and take Malfoy’s place.
If any of you recall, one of the kids overheard him arguing with Dumbledore over not doing something... and I’m positive it was that final “kill” scene.
Curious though...Dumbledore set his own death up...either planned or accidental. Hmmmmmm......
