Do you think there's no such thing as bad person?

To be honest I feel like everyone's bad person. I feel like no one can be good cuz at one point of your life I'm certain you felt like doing bad things as in disliking a person or not being kind enough etc or think about committing a crime. Or I don't know whether it's only me. Sometimes I think that if it weren't for my parents and religion I would have done all the bad things out there once  to have a taste of doing something bad and not right.

Comment to let me know :)
