There's fantasizing about hot chicks, and there's fantasizing about sex slaves. Doom is above that kind of crass sexism. His brand of sexism should be chivalry. Doom is arrogance, not hatred. You want a misogynist bad guy who's into the sexual humiliation of his female foes, you want Red Skull or something. Not Doom, who would consider that kind of thing the mark of a lesser man who couldn't earn voluntary sexual interest, who simply has too much class to treat a woman that way.
Not all bad guys are bad in all ways, or what the hell's the point of having more than one?
