Perhaps Becker’s greatest achievement has been to create a science of evil. He has given us a new way to understand how we create surplus evil—warfare, ethnic cleansing, genocide. From the beginning of time, humans have dealt with what Carl Jung called their shadow side—feelings of inferiority, self-hate, guilt, hostility—by projecting it onto an enemy. It has remained for Becker to make crystal clear the way in which warfare is a social ritual for purification of the world in which the enemy is assigned the role of being dirty, dangerous, and atheistic.
