That is one way, but their are more potent forms of evil. There is the Charles Manson/Son of Sam evil one can play. A Dark Jedi who hunts and kills his prey, as they are animals, then feeds upon the flesh of his kills. Capturing force adept young children, torturing them to gain the dark side corruption power then turn those who survive the tortures as instruments of death and destruction.
I can think of more evil and twisted things to do in a game, but I know Obsidian, WotC, and LucasArts will never in a million years do. Its the Bully evil and nothing else.
