I seem to recall some theory crafting of "If Vader had survived" and its basically this. Luke is the only one willing to really give him a shot and a bunch of people want him executed. Mon Mothma has him locked up (as much for his saftey as anyone elses) and basically lets Luke sneak out with him later when things start getting worse.
Anakin actually wants to die and isn't happy that he survived. Largely because he knows he's screwing up Luke's life and hes constantly hurting Lea by simply existing, so he was fine with being executed. But when Luke comes to bail him out he goes along with it, because he knows Luke isn't going to let them kill him.
The theory crafting ended with Luke and Anakin going off into space to study the force and possibly rebuild the Jedi, with Anakin going to find a way to redeem himself.
They are inspired by Nazis, of course they will.
