What happened to the majority of Nazi war criminals and their collaborators at the end of and after WWII? I am mostly thinking of people who did the killing directly such as SS personnel or camp guards. Were most of them killed? Captured? Escaped?
Here are some old answers on the topic, hopefully one or more of them will answer your question.
