Between victims and perpetrators was a band of prisoners who took privileges such as kapo posts, clerk jobs and Sonderkommando work in exchange for helping run the camp. The oppressor deliberately built this zone, because implicating victims in the crime spreads the guilt and breaks their solidarity. Levi argues their conduct should be judged with restraint, since the system first stripped away the conditions under which moral choice is normally possible.
Memories of trauma are not stored intact. Each time they are recalled they are reworked, filled in and hardened into a fixed story. Perpetrators slide from deliberate lying into sincerely believing their self-serving version, because a comfortable falsehood repeated often enough replaces the original memory. Victims also drift, avoiding the most painful details or taking on stories they heard from others.
Chaim Rumkowski was the Nazi-appointed Jewish elder of the Łódź ghetto. In 1944 he was sent to Auschwitz and killed there like the people he governed. Levi uses him as the defining case of how power, even when granted by an oppressor, intoxicates a victim and draws him into the oppressor's logic.
Those who survived the camps were mostly the ones who adapted, compromised, found privileges or had luck. The best people died, and so did the 'drowned,' the prisoners who hit bottom. Only the drowned could give full testimony, and they cannot speak, so survivors speak for them by proxy. This distortion in who is left to testify helps explain survivor shame, which is felt as if one had taken another person's place in life, even when no specific wrong was done.
Much of the camp's cruelty had no practical purpose. Examples include pointless bed-making rituals, the naked roll calls, denial of spoons and the transport of dying people in cattle cars without water. Levi argues this violence was an end in itself: humiliating victims until they seemed subhuman made killing them easier for the perpetrators to justify and to carry out.
