The entire prequel trilogy is whiny and childish because it represents a whiny and childish view of the world: that even bad people are good, and there are plenty of excuses that justify or explain their actions.
Not all “bad” people are black-and-white bad. Nor do all “bad” people think they are bad. Sometimes it’s dependent on point of view.
I didn’t know the man but I’m guessing Hitler had plenty of excuses so he could sleep at night.
This is not meant to defend the PT…or Hitler. The idea that “bad” is a point of view was one of the things I liked about the PT, but unfortunately it fumbled the execution.
