Feeling Lost and Hurt at Home, Wondering About Allah's Justice

Assalamu alaikum, I needed to share something heavy on my heart, it's really tough to talk about but I feel so lost. My parents have always been difficult, my dad gets violent with my mom sometimes, and then my mom ends up yelling at us or even hitting us too when she's angry. My dad doesn't always hit us, but he makes really scary threats a lot, saying he could cause harm, especially against my older sister since she was in her teens, now he's even starting to treat my younger sister the same because she reminds him of her. My mom keeps shouting and saying harsh words all the time. Things blew up again not long ago, and I ended up telling my mom that I can't stand her actions. I didn't dare say anything to my dad because I'm genuinely afraid he might act on his threats. My mom shouted more, obviously, but I just couldn't keep it inside anymore. It hurts so much-I'm angry that she doesn't stand up for us when she's mistreated by dad, one moment she tries to keep us safe, then she turns and makes things worse by getting mad at us and saying things about us. What's really hard for me is when they bring Islam into it, saying Allah will punish us if we don't respect them. But how can I respect them after everything? She's been calling me terrible things since I was little, and this has been going on for years. Will Allah hold my siblings and me accountable, or is it my parents? If their behavior is somehow excused, I don't know how I'll cope-I mostly feel miserable, only feeling a bit like myself at school. (And just to add, we're not perfect either-I've said things I'm not proud of, like saying I'd leave after school or that they shouldn't be parents.)
