The roots of evil: The origins of genocide and other group violence.

Staub, E. (1989). The roots of evil: The origins of genocide and other group violence. New York: Cambridge University Press.

In this book Ervin Staub, a professor in psychology, writes about the psychologal aspects of a genocide. At first he explains what genocide is and how this is different from a ‘normal’ war. Then he talks about the effect of difficult life conditions, cultural and individual characteristics that can lead to genocide, the psychology of perpetrators, bystanders and groups. Later four different genocides are being discussed which all share the above characteristics: the Armenian genocide, the Nazi Holocaust, the genocide in Cambodia and the mass killings in Argentina. This book is very interesting because of the explanation how people come to do these terrible acts that lead to genocide.
