Following on from your nazi example, its interesting to look at different people (and their potential alignments) and whether they colluded or resisted the regime. Here are some musings:
General von staufenberg - Lawful Good - Was lawful neutral up until the point he decided to try and assassinate Hitler
Contrasted with:
Adolf Eichmann - Lawful Neutral - the atypical military bureaucrat who followed his orders to the letter regardless of what they were
Communists - chaotic good - hated the regime and everything it stood for. Tried to subvert it to build a 'better' future
Contrasted with:
Catholics - True Neutral - looked after their own mainly - and turned a blind eye to the horrors of the regime
Social democrats - Neutral good - resisted the regime - some ended up in concentration camps, others didnt.
Oscar Schindler - Lawful good - was lawful neutral until he started to resist the regime
Karl Leibknicht and Rosa Luxemberg - chaotic good - communist leaders who tried to build a better future - were murdered by the far right Freikorps
It gets even more interesting if you were then to contrast that with Soviet Russia during the same period. Ironically in that instance you may well have people like:
Trotsky - Chaotic good
Lenin - Chaotic good (it pains me to even say that)
I think Stalin probably started off as lawful evil, and ended up neutral evil.
Well Stauffenberg had no real problems with Hitler until it became obvious how badly they were losing the war. Same as Rommel. Not many heros in the Wehrmacht.
Eichmann was a committed anti-Semite, ok more of a bureaucratic one than a headbashing one.
Catholics: Generally agree although there were exceptions like von Galen. Its record was probably better than the Lutherans, there was no Catholic equivilent to the Reich Church
Social Democrats: Individuals with individual reactions
Oscar Schlinder: In D&D terms started off true neutral, only interested in personal profit, ended up chaotic good, working against the regime
Since Stalin started off as a professional revolutionary and bank robber lawful evil seems unlikely to me
Where does someone like Artur Nebe fit? Took part in 38 and 44 plots against Hitler. also commanded an Einsatzgruppen.
Most people aren't good or bad all the time.
