It's not like Hades is even evil.
His job is not to torture you, he's just helping you into heaven/hell. He's literally a moving company condensed into one guy.
OK, sure, pinning your heart against a fucking FEATHER is a bit condescending, but those scales or the feather are magical, so you have a chance of getting to heaven.
Now that I think about it, he should be more of a patron saint of either justice, nihilism, or neutrality. It's not like he gives a shit about you specifically, his job is to just weight your heart, act scary if the feather or scales deem you worthy or unworthy of heaven, and move you into either. He's literally just a guy doing his job, he's kinda like a cashier.
