Kurt Vonnegut. Mother Darkness (№ 457999)

Quote Explanation: Mengel compares killing a person to tying a suitcase with a belt. As if it were the same thing - tightening a belt on a person’s neck and tightening a belt on a suitcase. If Mengel had not treated this with indifference and irony, the feeling of guilt would have eaten him from the inside.
