How does the prisoners' indoctrination benefit the Nazis in the novel Night?

The Nazis used hunger, fear, and violence to indoctrinate the prisoners into camp. The Nazis broke the prisoners down to their most basic animal instincts. They broke the prisoners' will to live, to worship, to be human. In Buna (Chapter 4), which was said to be a "good" camp, the Nazis starved their prisoners to the point of insanity. At one point during an air raid one prisoner gave his life trying to get some unmanned soup. With starved prisoners they are easy to control. The Nazis used fear through the hanging of pipet to "indoctrinate" the prisoners. They forced every prisoner to look the young boy in the eyes before they would give them food. Finally the Nazis indiscriminately beat people. Elie's father was beaten because he couldn't march in step, in actuality it was because Elie refused to give his shoes to the guard. The Nazis used any method they could to strike fear into the hearts of the weakened prisoners. Once the prisoners were "indoctrinated" the Nazis found it easy to rule the camp.
