Is evil contagious?

Here comes an update of the Lucifer post as there are new books on the market. Some want to understand (like Arendt or Amery) while others (like Nietzsche and Sartre) would strongly oppose. I am somewhere betweenboth parties with an increasing tendency to explain human (and corporate) behavior by social group pressure while there is still room by inborn personal differences. The 2007 Carnaghan and McFarland studies are giving further support to this view – there was a selection bias in the Zimbardo et als studies. On the other hand – crisis situations always call for strong leaders who need much less arguments to convince others than under normal circumstances that “others are evil” to justity their won distorted moral. It’s not the “Banality of the Evil“, it’s the “Complexity of the Evil” that makes it so contagious.
