Well they could use my idea:
You lead a group of Nazi soldiers. Like Mass Effect/Dragon Age, it'd be multiple choices and endings (all of which you die) and your men are shaped to your actions.
If you lead your men and fought against the Nazi regime (save Jews, refuse to execute people, etc) then you'd be given the kindest death of a cyanide pill and your men as well. They'll also be more reluctant to fight and would search for other solutions.
If you did as you were told, (kill Jews, execute people) then nothing changes and you die by hanging. Your men don't really care about anything and die by hanging as well.
If you went above and beyond and slaughtered/tortured for pleasure (beat Jews and people to death with a club) then you die by firing squad with you and your men giving one last, ''Heil Hitler!'' at the top of your lungs (then screen goes black and the sound of gunshots ring out) Your men don't hold back and are trigger happy, leaving no one alive that they cross paths with.
