Social psychologist James Waller uncovers the internal and external factors that can lead ordinary people to commit extraordinary acts of evil. Waller offers a sophisticated and comprehensive psychological view of how anyone can potentially participate in heinous crimes against humanity. He
outlines the evolutionary forces that shape human nature, the individual dispositions that are more likely to engage in acts of evil, and the context of cruelty in which these extraordinary acts can emerge. Eyewitness accounts are presented at the end of each chapter. In this second edition, Waller
has revised and updated eyewitness accounts and substantially reworked Part II of the book, removing the chapter about human nature and evolutionary adaptations, and instead using this evolutionary perspective as a base for his entire model of human evil.

The first edition of Becoming Evil spoke unforgettably to a world shell-shocked by 9/11 that faced a new war on terror against members of an Axis of Evil. With this second edition, James Waller brings us up to date on some of the horrific events he used in the first edition to illustrate his theory of extraordinary human evil, particularly those from the perennially troubled Balkans and Africa, pointing out steps taken both forward and back. Nearly a third of the references are new, reflecting the rapid pace of scholarship in Holocaust and genocide studies, and the issue of gender now occupies a prominent place in the discussion of the social construction of cruelty. Waller also offers a reconfigured explanatory model of evil to acknowledge that human behavior is multiply influenced, and that any answer to the question "Why did that person act as he or she did?" can be examined at two levels of analysis-- the proximate and the ultimate. Bookended by a powerful new foreword from Greg Stanton, vice-president of the International Association of Genocide Scholars, and a devastating postscript that addresses current outbreaks of genocide and mass killing, this new edition demonstrates that genocide is a problem whose time has not yet passed, but Waller's clear vision gives hope that at least we can begin to understand how ordinary people are recruited into the process of destruction.
