Is it normal to want to beat people up?

Of course -the disclaimer: you'll get in shit with your brother, your parents and if you do everything right -the police. Besides, morally it's wrong to hurt people. very enjoyable and satisfying, but very wrong. So might as well stay out of this.

Just check that there's no martial arts background, that they won't pull a knife on you and that you can actually beat them up.. if you can't -fight dirty, just knock out the strongest one in the bloodies way you can think of, chair, bottle, baseball bat and etc. Try to hit the nose -blood sprays everywhere. It'll scare the rest and you can finish them easily.

It's normal if you're being honest with yourself about what the problem is. Are they really that way or are you imagining it? I'm not in a position to judge... nobody here is.

So think about the situation carefully. If they really are like that, then get away from them. It's not safe for you, or them, for you to be around them. If it's just you, then YOU should take an anger management class.

Wanting to hurt people is relatively normal, especially when they hurt you. What it is NOT, is good.

It's normal for people to feel like that when they are operating on a base level.
Hang out with more chilled out and interesting people that don't wind you up or get into martial arts so you learn good techniques, respect and self-control.

I wannna be everyone up, people are annoying.

I guess it's normal but that dosent mean you should because you're the one that will get hurt the most, no matter how strong you think you are.

Stay away from them. You might get the crap beaten out of you! I think they have OD'd on testosterone.
