Specifically what do you think it is about you that qualifies you as either good or bad?
For me, I think I'm a good person because I'm an empath. I feel intense emotions in other people's perspectives and I feel that helps me to understand people better. Therefore most of the time I will position in my mind how my actions/words would be best said so as to minimize negativity. I don't actively seek to harm others and I don't consider myself to be better than anybody else.
I take that back, I do think there are people I am better than, but nothing to do with race or sex. Simply because me not wanting to hurt others makes me better than those that do.
On the flip side, I think I'm a bad person because if you've fallen off my empathy radar than I will never give a fuck about you again. Its harsh, and I can't help it, but if something happens to make me stop feeling emotions in your point of view then I can be devastatingly nonchalant as to what happens to you.
I like to add potential to the mix.
Consider on one hand a person who has a harsh upbringing and associated mental scars and hence realistically can only hope to be a slightly better than average person, at worst a plague on society, and turns out average.
On the other hand a person may grow up wealthy and well adjusted, gifted with intelligence health and charm, and realistically be capable of doing great things for the world. If this blessed person squanders their gifts and turns out slightly better than average, who is the better person of the two?
