one man ruining 5 lives

This is going to be an extremely long rant so apologies in advance to anyone who chooses to read it :))

I (20F) have 3 younger siblings, and along with my mother, we all have to face the scrutiny and tyranny of my horrible and disgraceful father. My hatred for him brews so much everyday that I am scared I will end up going into a full blown meltdown and kill him. He is a pathetic and selfish man who uses his power to abuse us. My mother is uneducated and severely depressed to do anything and help us out, I don’t know what to do either because I am in no position to get a job in my field since I am still studying in university, and the country we reside in makes it really difficult to be independent.

Basically back in my home country (the lack of system fails ya) my parents got married when my father was 27 and my mother was 15. She did not complete her education past the 10th grade, and was forced to move into a conjoined family system, my father has his business here (where we all currently live now) and would leave my mother with his siblings and his mother back in my home country. There she was subjected to their emotional and mental abuse, sometimes physical as well, whenever he would visit she would complain to him about what goes on and he would make things so much worse for her and subject her to physical abuse as well. We were all too young and little to do anything, after suffering for many years there my father decided it would be best if we got our education here rather than my home country, so we all shifted here.

My mother thought things could get better now that we were away from his family, I think it’s also important to mention that my mother’s family also failed her, they’re all broke and she had no home to go back to and unfortunately even when she could have left she chose to stay for the sake of her kids, but anyway, here she was also scrutinized so heavily by my father, he continued to get manipulated by his family and let them drive a boulder into their relationship. He would constantly berate her and not even give her any basic human decency. He thought he could just buy her stuff later on and make it up to her but it never did anything at all. He continued this cycle for years and years, now eventually he ended up cheating on her and got some whore to have fun with, he gives her respect that he never gave to my mother and she’s become so horribly depressed.

Everything that she used to do for him, me and my sister are now forced to do. We are forced to cook his food and clean his clothes because he doesn’t want my mother to do it anymore and she refuses to anyway. This drives a wedge into our education and entire livelihood, he bitches and moans about everything and anything. If the bread isn’t toasted properly he throws a little bitch tantrum and leaves the house without eating, literally of out 365 days if I mess up once he will hold onto it and berate me for days.

We can’t stand up to him because he threats to send us back to our home country and threatens to not provide for us, he has a horrible about of financial power over us and I just don’t know what to do anymore. I want to kill him and make him suffer so badly, I’m so lost.
