What should I do about my father?

I understand y you are having a hard time with your dad, but kinda tell him aside about you not liking what he does to your brother. Cuz i mean we all mess up a lot and probably if your dad keeps doing this to your bro and his own son, your brother will do something very terrible either law wise or to his own life. just kinda take your dad aside and tell him the possible consequences and if he yells at you just remember that he will actually think, hopefully, about what you just said and hopefully he will let up on your bro. And before you take your dad aside, just remember to pray for courage and also you need to respect your dad and not talk back to him or else you will not get anywhere with him. I'll be praying for you and your bro
