Nazi Germany's goal, from 1933-to 1945, was to "cleanse" the German society. Furthermore, those individuals that were viewed as a "biological threat" suffered from racial health policies created by Nazis. "The Nazi regime carried out a program of approximately 400,000 forced sterilizations and over 275,000 euthanasia deaths that found its most radical manifestation in the death of millions of “racial” enemies in the Holocaust." All of these actions, of course, were against the will of their victims.
