His medical procedures showed no consideration for the health, safety, or physical and emotional suffering of the victims.[3][4]
Rolf Mengele later claimed that his father had shown no remorse for his wartime activities.[48]
He was capable of being so kind to the children, to have them become fond of him, to bring them sugar, to think of small details in their daily lives, and to do things we would genuinely admire … And then, next to that, … the crematoria smoke, and these children, tomorrow or in a half-hour, he is going to send them there. Well, that is where the anomaly lay.[49]
Yitzhak Ganon, another survivor, reported in 2009 how Mengele removed his kidney without anesthesia. He was forced to return to work without painkillers.[58]
