I'll spot you Scarlet Witch, who is more the victim of her own despair than a sincere villain. But Killmonger's regicide and subsequent civil war never seem to do more than satisfy his own ego. Thanos is even worse. I almost prefer the incel-esque literally horny for death motivations over the dime-store eugenics.

I'll spot you that they're more well-spoken. They sound sophisticated in their delivery, rather than like some cackling madman a la Skeletor or Ming the Merciless. But then you stop to think about what they're actually doing, and its just tying damsels to the railroad tracks on a grander scale.
