I hate that the possibility of a complicated story/moral question died on the vine in the first ten minutes of TFA when a smiling Finn gunned down his former child soldier friends.
Having a black stormtrooper who wasn't an ideological Nazi was a mistake. "Actually the Empire are just normal people who are misguided!" No you liberal fucks, they're space Nazis and they're ontologically evil in a straightfoward morality play where good and evil are literally existing magic forces that let you throw rocks with your mind.
Fuck Dave whatever his nuts couldn't even stick it with the Clone Troopers. No, they're not psychologically conditioned from birth to follow the orders of their commanders. No, they're not slave soldiers who were deprived of any chance of experiencing a life that would allow them to develop mature ethics and independent thought. No, they have a brain chip that makes them evil.
I mean fuck me.
Apparently the old stuff had lots of clone troopers refuse to follow order 66 and there was actually a small civil war between Republican loyalists and Imperial loyalists, but Disney is like "Nah, let's side-step the whole issue and just say they used mind control".
