I'm laying out a novel's story arc, and I've run into a semi-serious problem: Identifying and writing for the motivations of my antagonistic characters. This is a future history story where the "bad guys" are a dictatorship like North Korea crossed with East Germany. Obviously such people have existed throughout history, from the border guards all the way up to the dictator(s) at the top, but what motivates such people? Why don't they just wake up one morning and say to themselves, "You know, this is a terrible thing I'm doing to the world." I'm having a lot of trouble getting "inside their heads" which of course makes it hard to write these characters convincingly.
Does anyone have any advice for writing these characters, and/or further sources for such information?
