Past come back to haunt me

So soon my sister's abusive ex boyfriend will be getting out of jail, I know where he is comming it's not a guess. He will be comming for my sister and me. I put him in the hospital last time, he might not be alone. Can I become a weapon again. Can I forget how to operate in society just to protect my family yet again? Can I take up the mantle of warrior again? Ready to die in battle stopping him and whomever he has with him??? I dunno this time. But I'm gonna try and if I meet my end I will make it such and end so that I will be worthy of my name and of memory.
