Quoting Edward B. Westermann’s Drunk on Genocide, page 135:

In addition to verbal jesting and mockery, the perpetrators incorporated physical abuse into acts of cruel humor. For example, an SS detachment from the German town of Heydekrug crossed into the Lithuanian town of Sveksna on June 27, 1941, in the wake of the invasion of the Soviet Union. The SS men amused themselves by shaving off half the beards or cutting off one earlock of Jewish men and later that night staging a mock execution of the town’s rabbi. In another case, an SS killer approached a girl in a group of Jewish women awaiting execution in the Ponary Forest by asking, “Look the moon is beautiful, and you, you are young and beautiful. Don’t you want to live?” The SS man, the commander of the local Gestapo, then told her to simply walk away, but not to look back. As the girl slowly moved away, the Gestapo man pulled out his revolver and shot her in the back as “the Lithuanians [i.e., auxiliaries] burst out laughing.” One uniformed policeman testified to the “sadistic joy” displayed by a senior enlisted policeman during prisoner interrogations. The policeman would have prisoners’ arms bent backward before firing a pistol at the victim’s elbow that resulted in a bullet traveling along the upper arm to the shoulder of the victim. In Rawa Ruska, Ida Steiner recalled how SS sergeant Helmut Späth, a man notorious for his daily killings, would “laugh” and tell the prisoners that “he felt no guilt since the Jews came to him themselves,” or he would quip, “Give me a cat or a Jew today.” One Jewish prisoner recalled [an Axis] official’s visit to the grave site at Chełmno: “He [the official] examined the corpses, talked to SS-officers and laughed.”
