There's something disturbing about a person who would find him acceptable.  When I hear their justifications, I get a sick feeling in my stomach. But I'm not at all surprised. This is us; they are us; this is humanity, and it's a problem. I've not believed that "people are good," or "most people are good," or "most people are basically good" for a long time. The field of psychology thinks it has a pretty good handle on the prevalence of personality disorders and mental illnesses, which addresses the prevalence of human beings without conscience, empathy, or a sense of responsibility. It's more than most people think.

The Milgram experiment is one of the scariest things I've ever looked at. It basically says that 66% of the general population will fatally electrocute a total stranger simply because another total stranger insists they do so. The victim can be screaming, begging, crying, but two out of three continue to torture. 

Some people are truly good. It's probably a bell curve.
