Upstanders and Bystanders The Holocaust

I think some people stood by and watched the holocaust because most people probably thought of it as if they stand up than the nazis are going to come after them. Something that inspires the upstanders to stand up to the nazis because they saw how they were being treated and the jews were being victimize. I would have probably not stood up because what if they try to come after me. We have learned about camps when the jews were being catched they were put in camps and being killed. I don't like how they were being treated just because of there region. If I was a jew I would want someone to stand up for me but I would understand why they wouldn't.
