describe a situation in the book where one or more prisoners became victims of other prisoners

The prisoners are annoyed with Eliezer's father for no other reason than he is sick and unable to share the work,

"My son, they are beating me!"

"Who?" I thought he was delirious.

"Him, the Frenchman … and the Pole … They beat me …"

One more stab to the heart, one more reason to hate. One less reason to live.

"Eliezer … Eliezer … tell them not to beat me … I haven’t done anything … Why are they beating me?"

I began to insult his neighbors. They mocked me. I promised them bread, soup. They laughed. Then they got angry; they could not stand my father any longer, they said, because he no longer was able to drag himself outside to relieve himself. (Chapter 8)
