What is a crime? A Jewish Surgeoun said to me the biggest crime of the Holacust was that the medical experiments were so badly done, nothing useful came out of them. To him, and I agree it meant all those who suffered, suffered pointlesly! There was no benifit to their suffering. Except from Luftwaffe hypothermia experiments, most modern treatment is based on that research. But survivors of the Holaucast benifited from the suffering during Indian Famines, treatments developed there were used to treat camp survivors.
One major problem of history, we are judging by OUR social norms.
