Holocaust question

Many people stood by because they didn't want anything to happen to them. I probably would of sat by and watched because I wouldn't want to get killed. If you were a up-stander you were risking your life. Many people did stand up though because they couldn't just sit around watching people get killed and token from there home. The up-standers would be very sneaky so they wouldn't get caught but even some of them did get caught and they would get killed.
