Hey Uptream,
I know how you feel. I used to teach a course that dealt with this exact issue. There's a documentry you should see titled Weapons of The Spirit. It is about a town in France, Le Chambon, that during the Holocaust became a rescue town. It is an amazing story, and it really helps to restore (at least some) faith in humanity. There's also a quote at the end, about human nature being fundamentally good with the potential to be fundamentally bad, and it's a chioce we make as individuals and as a society that determines which way we will go. Anyway, I suggest you check it out. If you can't seem to find it, PM me and I'll try to get it for you.
