If you never had fun with bullying others then you borned as good. If you actually had fun or don't really feel bad about it then you born as bad. I'm not saying which is good or bad. Just it determines who born as good or bad.
Other example, If you see a small bug and instantly want to kill it then you borned as bad. It varies on the situation. Ants, mosquitoes hurt you or your house. So kill is reasonable. If you see a rabid dog or fox if you can kill it with gun, then it's okay because you need to survive.
So except life matter or asset damage matter, if you just enjoy hurting then you born as bad. Even if asset damage matter, if you enjoy by killing it torture. Then you borned as bad. It's not right or wrong thing. It's a moral thing. And many countries don't care about moral anymore. Which is life is getting harsh day by day. It's like a disease. More people becomes bad.
