Am I problem or is HE the problem?

basically, my dad was yelling at my mother and cursing get her and it was not first time but I told him that it’s not right thing to curse your wife it’s very wrong. I told him that but he continued and I didn’t like it so I was like I was dead serious. I told him that if you curse my mother out again, I will curse yours and then he thought that I was not serious at all. I know I shouldn’t have done that, but I cursed out his mother I know I shouldn’t have done that, but at the moment he heard that he started to hit me. He was hitting me so hard that I ran across the room every time he hits me I’m going there and always kneeling down and always covering myself so I won’t get hit too hard, but he was kicking me with his Feet and of course it was hurtful but sometime past and I’ve realized that there is this one big question am I the problem or is HE the problem?

I would be grateful if you guys would answer my question, I need answer.💙
