If your child was an accessory or had committed the act of murder would you still accept them?

I know someone who has a daughter that’s an adult allowed her boyfriend to abuse and murder her child and shortly after the death she gets pregnant by the murderer. Although she didn’t physically do the heinous act she is an accessory to it because she was aware of what was going on and still allowed it to continue. Now I’ve discussed this with people in my daily life and I’m completely disgusted with her as a human being I don’t even feel she or him deserves to live but the decision is at the hands of God.
