Göring was a professed animal lover and conservationist, who, on instructions from Hitler, committed Germans who violated Nazi animal welfare laws to concentration camps. In his private diaries, Nazi Propaganda Minister Joseph Goebbels described Hitler as a vegetarian whose hatred of the Jewish and Christian religions in large part stemmed from the ethical distinction these faiths drew between the value of humans and the value of other animals; Goebbels also mentions that Hitler planned to ban slaughterhouses in the German Reich following the conclusion of World War II.
