<human>: I'm a male and studying at University for nearly four years and I don't live at home unless it is the holiday periods. 
My father has a very short temper and is very aggressive. He used to beat me, older brother and mother up when we were younger. Now he is older he wouldn't dare to try it now. He still has eruptive angry arguments where he will threaten to kill my mother or just shouts out her and tells her to get out of the house. I'm still dumbfounded that my brother and mother who still live in the house put up with this crazy behaviour. I have lived away for nearly four years on and off because of University and can't stand it when I'm living back with the family in the holidays. It's normally very small situations that make him snap. For example the tap not being fully turned off. In any other case it would be excused/dismissed by some other father. In my case my dad will go into a deep rage and get more pissed off about it ranting about water bills, he will class us(me, brother and mother) as being mental and pull out some other crazy bullshit. That was a real crap example but I hope you understand that what I am justifying is he doesn't operate rationally as a human. He will never talk out a problem instead but will choose the angry approach every time which involves cursing and swearing and shouting as loud as he can. When he is unhappy with someone he will rant to another person about the other offending person's flaws and what he thinks they have done wrong etc (He always thinks he is right as well). I have not asked him if he will seek medical help for his issues because I know very well he will just get super pissed off. If I get him compulsory treatment how will that affect him and my family? I would like to know what options I have. I suppose I could just move out forever and ignore my family. I live in the UK if that helps as well. Thanks

Can you give me the gist of the text in a nutshell?
<bot>: I have an angry dad. What kind of treatment can I get forced on him and how will that affect him and my family?
