I want to throw my 5 year old brother away?

Step away from the situation and think about this. You're equating your brother's life to tabs on a computer that can likely be retrieved. He's also five years old. He doesn't understand the world and makes mistakes, just like you probably did when you were five! Hell, when I was little I went in my mom's room while she was doing laundry and threw everything I could out of the window (money, her phone, her bras and underwear) for the neighbors to see. I can only imagine how frustrated she was, but because she loved me she sat me down and explained how what I did was wrong. I got punished, but she didn't toss me out for making a mistake.
I advise you to be patient. Kids are irritating but they're learning. Tell your parents so he gets a punishment, cool down, and talk to him about how you feel and why he shouldn't do that.
