Abusive father

I am writing this in behalf of my mother. Because she can never tell . My father is abusive towards whole family.(me and my sister and my mother). I cannot handle this my father always scolding my mom and telling us(me and my sister)that we are illiterate and can't do simple basic things . He always tells us that he is the man of the family and should not told by us(all three) to what to do and what not to do. When he got corona in last month he scolded my mom because my mom simply told him to do corona test as he was ill. He scolded my mom that why she tell him to do corona test. And when he got the test positive and was in different room ,he said that I will not wear mask as I already got the corona. Means he cannot even understand basic things and tells us to do basic chores. What kind of man he is ? My mom doesn't like non veg . But as a wife makes it as she thought it is her dharma. But my father always thought that my mom make faces when he eats or bring non veg in home . Means that she is cooking for you and you are abusing her . I don't understand and i cannot bear it. He thinks that we(me, sister,mom) held him in the house for no reason. But we(me, sister,mom) think that as he was recovered from corona he must not go outside. We know he gets bored he must entertain himself in house as ther are many ways . I am a college student and my college aren't even open as I am a 1st year student ,he(father) can roam outside . But he never wears mask and when we told him to wear the mask he uses abusive words and scolds us that will you kill me if I wear mask . I didn't went out since corona . I am a teenager who wants to make his dreams come true . But he didn't understand it also. I don't know what kind of thinking is that. We told him to be nice towards us as we have only him and he got only us. All in all please make my father understand that in this cruel world no one comes for him but his only son, daughter and wife will help him. And raising voice doesn't mean that you are right. You must listen what other person is saying . I don't know what to do because I don't have any one to like after me and vice Versa. He always thinks that we never respects him . Means he didn't even think before saying it . We plead him like God but he always thinks that we speaks in good tone with outsiders but not with him. As a teenager I cannot handle it because I don't want to ruin my future . Because no father tells his family that he is the one who feeds us so do as i (father) says. Means everyone is taking care of there children but never say such hard words. And will punish if we didn't do as he says. To treat him like a king . Bring him what he want whenever he wants. To leave our(me ,mom, sister) chores and do his work. We never did and we will never will.
