Faith in Humanity?

Is it really possible to follow someone to your demise, knowing they're going to kill you if you fight back? However, many people do, because they have faith in humanity. But, think about it like the holocaust... the prisoners would follow the Nazis to the gas chamber, but if they fought back, they would be shot. Some fought back, but most just walked to their dooom, because they had faith in humanity. So think about it, can we afford faith in humanity? Is there even such a thing as humanity?
