Too Aggressive And Vindictive

Hi, I'm 22, girl. I have a brother of 16. We are from completely different parents, just his mother and father got married 7 years ago, but I love him very much. However, he is becoming more and more aggressive. From an early age there were slight nervous outbursts, but with each passing day they began to turn into aggression. He was enrolled in boxing to have a place to vent his anger, but I think that made him even angrier. He watched boxing and mma all the time, he didn't care about movies and non-violent games, and he still does. He trained boxing for a while and then decided that he liked MMA more. Ours recorded him and he became obsessed with the idea of ​​becoming the best. He trains constantly, even misses school to go to training. And when he's at school, his classmate calls his mother because he's aggressive. When our people start talking to him to reduce training, he goes crazy and does not want to hear at all. He constantly says that he will find his father and "show him" everything he can. His mother tells him that this is complete nonsense and then every time he asks her if he remembers how he treated them, how he beat her when he got drunk. He says he couldn't protect her then, but that's not the case anymore. He doesn't let anything be said to him. If someone raises his voice, he explodes. He hasn't touched any of us yet, but I'm afraid he might one day. I really want to help him reduce aggression and irritability, but I don't know how. how he beat her when he got drunk.
