Who Goes Nazi? (1941)
I get what the author is getting at.  Not sure I agree.  Many years ago, I read "Ordinary Men: Reserve Police Battalion 101 and the Final Solution in Poland", which analyzes interviews with the actual men performing the slaughter of innocents at the end of the war.The conclusion that book drew was different than this article, and makes more sense to me — that it's not "mean people 'go nazi'", but ordinary people who 'go nazi', given a system which relieves them of responsibility for their actions.  "Just following orders" was the typical & honest answer, if I recall.  The men didn't feel they bore a moral duty to disobey, because these things just had to be done, or so they were told.So, if I can riff a bit on the article's themes... maybe mean people will hand you the gun, but anyone will pull the trigger, if they're told to do so.
