I think they're mostly right but their uncritical embrace of the seven deadly sins of a concept is pretty weird. Also the idea that one has to be good "for good reasons that are entirely selfless" is kind of weird too. It's normal and good for people to have pride in not being a bad person, actually. The bad part is when you base that pride on falsehood (and pride is not the same thing as feeling superior to other people)

Of course it should also be based in actually caring about other living things but that's like, idk kinda of assumed I thought
