I was born with that kind of bullying mentality. It feels good to bully. What kind of psychology is this?

Bullying is a kind of psychology that most people have, so you don't have to blame yourself. It's just that when people grow up, they should learn to treat them rationally. Being aware of such problems shows that you are a person with strong self-awareness ability. I believe that when you encounter such a thing, you will immediately participate rationally and manage your words and deeds. You must be great.
