Threatening him

So I’m 21 and my brother is 23. He’s refusing to go to work; Don’t know why. My mom is sitting here calling him a pussy, pretty sure she broke his phone, and is threatening to take all $10,000 out of his account (she’s on both our accounts). Her screaming at him woke me up (it’s 5am). I’m more worried about how my dad is going to react when he gets home later, so I’m leaving the house this afternoon and I’m not coming home until LATE late evening. I’m only leaving because he gets VIOLENT when he’s pissed off, he spikes my fight or flight like all fucking hell, and he’s not afraid to get in your face to scream at you. I’ve never seen him get physical when he’s sober, (drunk, yes. Both me and my brother have felt his wrath when he was drunk), but I’m pretty sure it’s 10000x worse if he does later. I won’t be surprised if everything expensive in my brother’s room is broken. I don’t know how he has the balls to refuse work when he knows our dad is going to get VERY pissed off later.

Ive recently moved back home due do to my ex, but I’m moving out again sometime next year so I’ll be out of this situation. My mom specifically sat there and lied to me about how all the drinking, the fighting, and all the violence stopped when they wanted me to come home. They sat there and lied to my face. They put up a show whenever I came to visit. They stopped drinking for all of 2 weeks and then picked up their old habits like I had never left in the first place. I’ve contemplating just living in my car homeless because I don’t want to be here anymore
