I'd rather die as a good man than live as a monster so I would have tried and be a member of the resistance (hide jews in my house, sabotage etc). But you never know, it's a difficult question.
Governments are so responsible for this tho it's disgusting. Like literally every country knew what was happening but they closed their eyes because:
1. they wanted Hitler to like them (**** u Pétain!!)
2. Were pieces of **** themselves
3. They didn't want to get involved in the war if they weren't threatened (hi USA).
EDIT: I don't think people knew that as a whole they could go against the government at that time. Members from the resitance knew and tried but a lot of them got killed, tortured etc. Damn I hate that era so much, i'm so tired of hearing about it. it's just show how ****ed up we are.
EDIT: a lot of people actually thought this was the solution to their problems that's why they helped. Like kill all the jews so the economy will rise

, the brainwashing was real.
