Totalitarian regimes produce a culture and a moral code that is totally different from what happens in a democracy. There are two moral categories in a communist society: honest men and bad men. The "honest" ones resist compromising or collaborating with the regime, while the "bad" are the persecutors and collaborators. You can choose to be on one side or the other, but there is nothing in between. In a normal society, other factors can define who you are. You can be a good worker, sociable, tough, generous, tolerant, collaborative, friendly.
