What makes a good person?

Are people good because they don't say, do or think bad stuff or are people good because, even though their thoughts are corrupted, they don't act or express them? Is a n@zi a good person if they don't ever, in any way, express their hatred?

I consider myself alt but often find myself judging people. Still, would never say it to their face nor do anything to them. Still, they don't deserve bad things just because they're "cringe" or something (obviously).
