Should i do suicide

I have seen to my father beating my mother since childhood. He has some problems with is mental condition (i think, he is not normal person). In every tiny matters, he behave extra.. We (me, my mother and my siblings) always lived and live in fears as we don't know what will he do in very next time.. I am 21 year old and looking for government job. My father is a labour , he work in GAS AGENCY. He always showed us that he is doing favour to us by educating us or by giving us food. He is very judgmental and he thinks that he is superior than everyone living near by him. Does not matter, how wrong he is but he always justify his action.. We are still living with him because we don't have any financial support. I am elder in my siblings. My mother doesn't has her opinion, she thinks that she has to live like that till she dies. For example of our condition::: ---- In the morning of 8-aug-2019, he was going to be ready for his job suddenly he didn't find his facial cream. He started to yelling at my mom and at us. He was going to kill my mother with the object he was holding at that time (however i was standing their so he controlled himself). Everyone me my mother my younger sister was busy in finding that cream, we were finding it in order to avoid this heated situation. Meanwhile he started to mention his beneficence he did to us, by educating us by giving us food. He was regretting that he spent 80000 per month on our schooling (he always regret about it). He asked not make breakfast for him otherwise he will destroy house.. And then suddenly i got that facial cream which was just near by his things.. But he was not even sorry to us , not even regretting (as he do always), and later he went to his job. I am sure he well accelerate this matter when he will be back at home and he will try to frame himself as innocent one. And it's us who are doing all mistakes and making our life blunder. I have lived my whole life like this (in fear) since i have grown. My mother is just passing her time waiting to death. Should we continue this? Because every father do this. Is not mentally torture? I am force to think how to suicide!!!!! Should we do same as we are living quki chaar log kya kahege (what would people say)???
