Let's first start with the people calling for this then we can revisit the idea afterward.
Nazi leaders were noted for love of their pets and for certain animals, notably apex predators like the wolf and the lion. Hitler, a vegetarian and hater of hunting, adored dogs and spent some of his final hours in the company of Blondi, whom he would take for walks outside the bunker at some danger to himself. He had a particular enthusiasm for birds and most of all for wolves. [...] Goebbels said, famously, ‘The only real friend one has in the end is the dog. . . The more I get to know the human species, the more I care for my Benno.’ Goebbels also agreed with Hitler that ‘meat eating is a perversion in our human nature,’ and that Christianity was a ‘symptom of decay’, since it did not urge vegetarianism. [...] On the one hand, monsters of cruelty towards their fellow humans; on the other, kind to animals and zealous in their interest. In their very fine essay on such contradictions, Arnold Arluke and Boria Sax offer three observations. One, as just noted, many Nazi leaders harboured affection towards animals but antipathy to humans. Hitler was given films by a maharaja which displayed animals killing people. The Führer watched with equanimity. Another film showed humans killing animals. Hitler covered his eyes and begged to be told when the slaughter was over.[29]
