How would you prove evil exists? How would you prove reincarnation?
You tend to make a lot of definitive statements as truth claims without supporting evidence with some logical fallacies thrown in (like appeal to authority with "every spiritual person knows").
Claiming Bill Gates has participated in genocide and should be locked up for it is quite a claim. I do know some vaccine trials were terribly immoral. Was that directly on Bill Gate? Did he knowingly do that and is there evidence to prove it? Please explain what you mean by "(whether he has knowingly done this or not)" because if you're advocating for a justice system which locks people up for things they don't even know they did, that, I might agree, could be evidence of the existence of evil.
