Mengele in a time period between his first arrival and the liberation of Auschwitz did uncountable numbers of experiments on humans at the Auschwitz camps. He did experiments on twins, women sterilization experiments, surgeries without anesthetic, inserted diseases, tested how long until people died under certain circumstances, and many other absolutely detestable, unbelievable, and mind-chilling experiments. He was nicknamed the “Angel of Death,” because he also was quite often on duty to decide who was going to live and who was going to be gassed or experimented on. Many consider Josef Mengele to be one of the sickest, twisted, psychopathic people to have ever existed.
