I believe people can be good in different ways. I had a friend who had some batshit insane religious beliefs (Baptist), like she said it was worse to kill yourself than someone else, because then you couldn't repent. But she would do anything for a friend, I had an emergency and she kept my kids even though she had a job interview, as an example. So she was good in actions and I'd argue evil in beliefs.

I have a coworker who is so mean & cutting, complains relentlessly about her husband, prickly person but does a great job at her job, loves her dog, and is great to work with because she Gets Shit Done. Is she good? Bad ?

I guess my bottom line criteria is can you care about others in at least some way, so empathy or sympathy is what makes it possible to be good.
