"Ordinary Men" is a historical account by Christopher R. Browning that examines the actions of the Reserve Police Battalion 101, a group of German police officers during the Holocaust. The book explores how these ordinary individuals became perpetrators of mass murder in Nazi-occupied Poland during World War II. Browning analyzes the psychological and social factors that led these men to participate in the atrocities, despite having the option to refuse. The work highlights the complexities of human behavior in extreme situations and raises important questions about morality, conformity, and the capacity for violence within ordinary people.
