Do you think you’re a good person?
Sure, but that’s not the right question.
I’m human. I’m capable of both good and evil, to the extent that those concepts even have meaning beyond our limited moral comprehension of the universe. I do what I can to alleviate suffering and add some measure of benefit to this bizarre little experiment we call a world, but it’s all ultimately insignificant.
It doesn’t matter whether I think I’m a good person. It only matters whether I am good to other people.
