Life is super boring. This is making me want to hurt people just to mix things up.
I hope you're joking about hurting people for entertainment. Why would that appeal to you?
Hurting people makes me happy.
If you are feeling inclined to hurt people, don't, it's wrong to hurt others. Hurting others will eventually get you into trouble.
Nah, I don't think I'll get in trouble.
It's very likely that you will indeed end up in trouble if you go around hurting people for kicks. If you have frustrations you need to find a different way to get them out that doesn't include other people. Maybe you could get a punching bag, but not a human one.
