Is it normal that i hate my brother?

I already know that it's normal; hating my brother. I guess I came here just to hear someone else's stories. I have nobody else to turn to and everywhere I search on the internet I get no answers on how to solve my problem. My brother is absolutely out of control. My parents have no power over him. He is 18 years old and I'm 20 and in college. Being in college makes things so much better because I don't get to see him most of the time. However when I come home for the holidays, I realize how fucked up my situation is. He smokes weed and has an uncontrolable temper. Whenever he is doing something wrong, my parents are scared to tell him anything and if I do it, it just makes things so much worse.

I have a grudge against my mom as well. She cannot control him but when I tell her to throw him out, she just says that she can't do anything because he is her son. But seriously, I feel unsafe when I come home. I really do. He is a real threat to my family. He wants everyone to respect him, when he has never earned our respect. But I understand those type of people. Don't think that I don't. People like him demand respect because they are worthless pieces of human trash. (I have never said this to him, so don't think that his behavior stems from this.)

He will never go to college and I am in college because of a full-ride and hard work in high school, nothing else. What I am saying is that it is difficult coming back home extremely excited to see your parents after a difficult semester and have that all go to shit three days into a long, long winter break. If they didn't close the residences I would be back in college tomorrow. But I am trapped. My mother is not the only one trapped. I have to find a way to deal with the fact that my parents will always enable their bastard son. No matter how successful I am, and try to help them out, they will always want to look out for their useless son. I am mad that they can't control him. We live in a 1 bedroom apartment with no room for privacy. I come home and I sleep in a couch. It's not like I can lock myself in my room or anything. He always blames others for his mistakes.He is the lowest piece of shit that you could ever meet.

I'm also mad about the fact that there is really nothing to do. My parents aren't strong enough to control him, and I can't really call the police either. What am I going to tell them? My brother is listening to music super loud at 10:30 pm just because he is pissed with us? (That is what he is doing right now, and it doesn't sound like a big deal, but there is more to it than that). What bothers me is that my parents told him not to play it so loudly and because he has a problem with authority he turns it up even more. I know I said that I held a grudge against my mom, but it's not that big of a grudge. It just bothers me to an extreme extend that they can't even command basic respect from him. One time, very long ago, we did call the police on him for a legetimate reason and it was a complete disaster. The reason was that he was grabbing things from the apartment and just throwing them in the backyard, he had a knife and he was smoking pot. We were in danger.What do the police do? They didn't take him. They just said that they couldn't takd him and they released him to us right there. He made such a huge scene about my mom calling the cops once they left you had to be there to see why I feel unsafe.

If he died, I think I would smile. I'm not saying that because I'm angry, I really do mean it. Nobody needs him. Both of my parents have health issues and I can't help them either because they can't help themselves. The only thing with him dying is that funerals are expensive. That's the only downside. He doesn't do us any good dead or alive. I guess this is life. It sucks. One day though, I will take my parents far away. One day he will need our help, and I will spit in his face.
