Is it normal to want to kill own father?

Do it.

I feel the same exact way about my father. The abuse he put me and my sister through still haunts me almost 30 years later.

I know exactly how you feel. My father did the same thing, beat my mother in front of me, and told me I was worthless everyday, and he even went out of his way to tell me that. But I pity him because he's a pathetic loser. I understand how you feel, but your brother needs you and killing your father is going to hinder that. Just remember he's not the one being kept up at night by the things he's doing; you are. Just let it go.

I won't kill him, though. Because, my 2-years-old brother heavily depends on me. I have responsibilities to my brother. He is now well, recovered from illness.
The main problem is, whenever my annual exams begin, my father starts to quarrel and beat me and my mother. He uses chair to beat me. I have an elder brother who works in UAE. And, even the fees of my exams have to be paid by my elder brother. Despite working in foreign, my brother's income is less than half of my father's.

I could kill mine... He's an asshole... Just ignore him and avoid him.. don't get into trouble over his dumbass
