Couldn't the same be said about the OG Nazis? All of their medical "experiments" on prisoners of concentration camps [1] were unethical, there wasn't even anything of note found out because they were either shit at documenting "experiments" or the "experiments" were just the personal dreams of sadistic "doctors".
There are lines we damn well shouldn't cross, and where it is worth we should sanction violators. We are supposed to have learned from "historical Western traumas and sensibilities", because if not then all the suffering would have been in vain.
