Why did dr. josef mengele do the experiments?

Dr. Josef Mengele conducted experiments at Auschwitz primarily to advance Nazi racial theories and to explore medical practices that aligned with his interest in genetics. He aimed to identify traits that could be used to promote the idea of Aryan superiority, often subjecting prisoners, particularly twins and those with disabilities, to inhumane and unethical procedures. Mengele's actions were driven by a combination of ideological beliefs, a desire for scientific acclaim, and a lack of moral restraint. His experiments resulted in immense suffering and are considered some of the most egregious atrocities of the Holocaust.
