The German concentration camps depended on the cooperation of trustee inmates who supervised the prisoners. Known as Kapos, these trustees carried out the will of the Nazi camp commandants and guards, and were often as brutal as their SS counterparts. Some of these Kapos were Jewish, and even they inflicted harsh treatment on their fellow prisoners. For many, failure to perform their duties would have resulted in severe punishment and even death, but many historians view their actions as a form of complicity. After the war, the prosecution of Kapos as war criminals, particularly those who were Jewish, created an ethical dilemma which continues to this day.
