AITAH for planning to move out?

I (F18) live with my brother (M30) and father (M50) in our family house alongside with my two sisters (F12, F15) and mother (F48). When I was about 16 I and the rest of the family found out about my brother's addiction and his abusive tendencies started to make more sense (he would throw regular unprompted tantrums, be extremely paranoid and blame us for things we didn't even think of doing, not to mention the systematic abuse that took place). It's important to mention that my jewel of a father made no efforts in stopping this nonsense even before finding out about his addiction, blaming the "females" (his own words, though they were much harsher) of the household for provoking his son, essentially allowing my brother to continue further. I tried to tough it out for the sake of going to university and moving out as soon as possible as to not be left without a higher education in a country where I could hardly find a job as a woman, let alone as an uneducated woman. My brother, however, started to get physically abusive and my father, again, refused to step in, and long story short he beat my youngest sister up so badly that she landed in a hospital with a broken rib and a fractured skull. The reason? She refused to pass the tv remote the moment he demanded it (she was watching cartoons while our dad was out since he does not allow us to do anything besides housework when he's home). He got away with it thanks to my father's ties, and I decided that enough's enough, I'm moving out as soon as I get everything sorted out. Somehow my father found out about it (I'm suspecting one of our relatives somehow overheard it and snitched on me) and is now blaming me for "running away" and leaving them when times got tough (I'm not planning on leaving my mother and sisters, just them two). AITA?
