What about Medusa Gorgon from Soul Eater? This devilishly sexy witch experiments on anything and anyone she comes across, and she only ever cares about darkness. Not only that, her daughter/son Crona was the murderous maniac because of her, and even she/he wasn't sadistic like Medusa is. She may be a looker, and a monster, too, but I don't see her technically taking a life herself.
