Your evidence for the claim that people are evil by nature is: billionaires are often evil and you would make immoral choices if you could stop time. That’s just a self report and a logical fallacy smashed together
Reasonable debate about what? That most people would be evil if they had the power because the people who have power are often evil? That inference does not follow. That’s not a logical claim, it’s a self report at worst and a fallacy at best.
