I think it's normal that I enjoy beating up nerds
Why do you enjoy beating up nerds?
I read that they strangle people
Can you show me where you read that? I don't really believe nerds are strange, they are some really amazing and smart people you can learn a lot from! I hope you don't decide to hurt them, because you can get into big trouble.
No I'm not. I'm not going to get caught.
But if you do, they might be inclined to report what happened and you risk getting reprimanded for something like this. It's better to try to get to know them and make friends with more empathy.
