Everyone is a bad person who does good things, not a good person who does bad things.
I disagree with this. Original sin and born as sinners is a Christian notion and while you arent directly saying those terms you are using the idea here.
I think your actions are what determine your character, not that you are born evil and sometimes do good things. What I would say are the bad things that someone can do stems from my previous posts, essentially anything that hurts anyone else in some way is bad.
