How did Mengele's experiments show his devotion to the Volk?

Question

I already have how he attempted to genetically engineer twins and how all the experiments were to "help" soldiers.

Answer 1

From what I've read of Mengele, "devotion" was no where to be found in him. Mengele was an opportunist. It was like a student doctor that arranges to get his own cadaver to explore the human body the way he wants to. Mengele did it with live bodies, assuming there would be no consequences. There was nothing so altruistic about Mengele.

The word devotion was applied to Mengele's teacher, Verschaur in Heredity and Infection: The History of Disease Transmission by Jean-Paul Gaudillerie and Ilana Lowy (Routledge, 2001), p. 61. Mengele sent him body parts and reports. That was more of a devotion to science, hang the human cost.

Answer 2

In his weird and sick way, many of his experiments were that any doctor would want the results of, but couldn't morally do themselves.

He didn't genetically engineer twins he selected twins so he could do something sick to one and use the other as a control.
When the first died because of one of his sickening experiments he would have the twin killed.
The autopsies performed were to show what had been damaged or had failed.

he could have been a good doctor, but he went over the edge of decency and morality
