[Qlippoth]

My favorite villain would have to be Kergan from the game Arcanum. Yeah, he wants to destroy all existance, but he believes it's for a good cause, and I was really moved by his monologue before the battle.

A note on sephiroth: I've never played FF7, but I think he has to be the most hyped video game character ever made. Any Quabbalist can tell from my name that I don't like him.
