Tortured Child of A Demon and Angel

A man who is half angel half demon. He witnessed his father slaughtered in front of his eyes. He watched as his mother was raped by countless men and then butchered like an animal. He was enslaved by angels and beaten for fun. He was raped by men and women. He was trained to be a weapon for murder. He was betrayed by demons when he finally escaped the angels. He had everything taken from him. He was filled with rage and never stopped killing until angels and demons became extinct. He never knew life outside of torture and killing. He wandered outside the realm that used to house angels and demons. He entered a place where no angels and demons were. What will happen to this man with nothing left?
