I want my brother dead

I hate my brother so fucking much. I really do wish he would drop dead, and not in a peaceful way. I am not religious and see and analyze things the way they are. Life would be SO good without him. He makes me feel uncomfortable being home and at school. He has turned people against me and I can't stand it. He is so fucking mean to my parents and my grandparents and they would be much happier without him. Currently, someone at school is accusing me of doing something and she was (so I thought) someone we both hated mutually. He believes her. So this is making us not talk, and my parents are getting aggravated because we are not talking. I put up with his derogatory comments and bullshit for so fucking long, so what's wrong with me cutting him off? He harrasses people because they're feminist, fat, ugly, or because of their races. He makes everyone feel uncomfortable or bad about themselves. My parents don't understand that I'm trying to make my life a little bit happier by avoiding him.

Also, they commend him for every little fucking thing but not me. They don't see through his bullshit. I'm at an Ivy League university but that doesn't matter. I don't/didn't get seven thousand fucking tutors like he did, but that doesn't matter. He's a pathetic, naive piece of shit who can't treat anyone right, but that doesn't matter. When he does something wrong, I ALWAYS somehow get blamed for it.

I wish someone would kill him already.

I know some people don't think this is normal, but others do. People who share a similar situation, how do you deal with it? Did you cut your sibling off? I can't take this anymore. My parents are making us both go on a family trip and I'm going to get yelled at so badly for not talking to him, but it's only for my sanity.

I wrote another post explaining more, but the situation is really bad. But I'm getting super frustrated with him and my whole family.

Edit: I can't move out because I'm a high school senior.
