Going completely insane does tend to distance you from any "human" state. Just look at the Joker, more specifically the Kevin Michael Richardson iteration (that's the one from The Batman). It's implied he was as normal as anyone else until he fell into a vat of chemicals, whereupon he went nuts and, you could say, lost his humanity- and all the good traits he may have once had.
