[quote]Mm, in this RP I don't think sob-story motivations or existential angst are really anything to have to worry about-- we're all here for the same reason. Just that when one typically imagines a villain, it is usually a Guy who Wants Something. Easier to write around than a Something that May Or May Not Want Anything, you feel me?

I think that's exactly what makes the best villains. They know what they want, and what makes them villains is the ways they try get it. Doesn't matter to me if they have a "sob story" or they're just plain lunatics, it's better to have diversity in each villain's motive instead of everyone being "mwhahaha, I have the power, hence I have to rule over all". Heck, villains are the heroes of their own story. Some of them might think this is for a righteous cause.

I believe so far every character I've read leans more on the side of "doing what's best for their own interests and world" than just being plain homicidal. Not that it's a bad thing mind you. I also can appreciate the trope of a psychopathic maniac causing mass genocide just for the fun of it.
