"Hitler's Willing Executioners" is a term that refers to the ordinary German citizens who participated in the Holocaust, often motivated by a mix of ideology, peer pressure, and a desire for social conformity. This concept is explored in the book "Hitler's Willing Executioners: Ordinary Germans and the Holocaust" by historian Daniel Jonah Goldhagen, which argues that many Germans were complicit in the atrocities committed against the Jewish population during World War II. Goldhagen's work suggests that a unique strain of anti-Semitism in German culture contributed to this complicity, making it easier for individuals to justify their actions. The book sparked significant debate about the nature of guilt and responsibility in the context of the Holocaust, challenging the notion that only the Nazi leadership was to blame for the genocide.
