Auschwitz III (Monowitz).

Elie's father helped him after he suffered one of Idek's bouts of madness in the camp. His father was a source of strength and support for Elie during their time in the concentration camp.
It was ironic that Elie felt relief when his father was beaten by Idek, as he didn't want to be the target of Idek's violence. This demonstrates the extreme dehumanization and survival instincts present in the concentration camps, where one can find relief in seeing harm come to a loved one instead of oneself.
