So, my little brother is 15 and he and our dad fight a lot. Whilst my dad definitely has issues with anger, he's gotten a lot better over the years at controlling himself. My brother is super annoying, as most 15 year olds are, but he seems to go out of his way to not get along with our dad. He then talks shit about our dad a lot, saying that his life would be so much easier if he was there, etc. They have not gotten along for as long as I can remember. 

Like I said, my brother provokes my dad a lot. He does things he's been total countless times not to do, and any time he gets told off for something (which is often) he twists the situation to try and argue that it's not his fault, when it clearly is. I've had long discussions with my parents about it, and it's apparently something he's done since he was a toddler.

He and my dad often fight when my mum isn't home (she usually defuses situations), and it escalates quickly without her there - leading to my dad swearing at my brother and saying a lot of nasty stuff to him, and my brother refusing to back down or just accept that he made a mistake and move on.

Now, I am NOT condoning my dad's behaviour. I hate it. However, it would not come to that if my brother was not an ass and if he just accepted that he did something wrong. If he just said 'yeah, I'm sorry, I'll try not to do that again' it would be fine, but he tries to make up excuses about why he did what he did so he can wriggle his way out of it, which never works.

Anyway. When they fight, my brother often comes crying to me to try and protect him or take his side. I'm a 19 year old girl, a lot shorter than him and my dad, so I can't do shit to protect him. If I say something, my dad will get angry with me as well and it'll make it worse. And most of the time I don't want to take his side either - usually because it's his fault, but sometimes just because I don't have the energy to deal with it and I just want them to stop fighting. I've had a lot of exams recently and I've been studying a lot, and I'm emotionally drained. 

After/during the fights when I don't back him up, or if I call him out and say it is actually his fault, my brother gets really upset with me and asks why none of us care about his feelings and about our dad treating him like shit, and that if I said something our dad wouldn't be as mean. 

so, AITA for not 'helping' him when they fight?
