How to deal with sexual assault ?

Hello, I need help with dealing with sexual assault that happened to my sister and my mother, not by the same man but they were assaulted by family members when they were younger. I was never sexually assault, and I hurt for my mother and sister, I knew it happend to my sister but I recently found out that it happened to my mom when she was a little girl. And now I want to kill these men but I know it's not the right way, although I do have a daughter of my own, I understand why my mom tells she not to think about it because if I was sexually assaulted like my mother and my sister I wouldn't want to tell my daughter in fear that she would have to carry that hurt for me, just like how I carry my mothers and sisters assault. What helps ?
