Hitler introduced better protection for animals. I’m not going to say I like him, but I’m with him on this one.
He also gave up his inheritance to his single mother sister. Overall his bad dominated his good and he deserved a humiliating death like Mussolini or Gaddafi, but there was some good there.
Though it’s interesting that Trump’s “good” is a grammar preference. Trump isn’t more bad than Hitler but he might be less good.
