I mean even Hitler was adored by some in fact millions. I am not so sure about that. But there was still underground resistance. History is full of rebellion for freedom. People who wish freedom fight to be free.
Morality is constant.
In fact there were far more collaborators then resistors and ten times as more passive elements that accepted Hitlers status quo in the occupied countries. The reason Hitler was defeated was the mistake of a two front war. And hardly had anything to do with morals. Your theme is very romantic but in the final analisis it is the violent overthrow of one society by the other which decides the moral code. Back to the relationship of character to morality.
