Bitter ex sister in law.

I need help on giving my brother the best advice i can so here is the story of whats happening. My sister in law has cheated on my brother multiple times “3 to be exact” as far as we know. Well he let it go bc there was not enough proof and he wanted his family back and she of course denied all allegations. Well the third time around she got caught red handed by some of my brothers friends who noticed what was going on and contacted him . They sent him pictures, videos even screen shots of the conversations she was having with this other guy, my brother was crushed honestly i never seen him like this and now that he decided he wants nothing to do with my sister in law she is withholding their daughter . He left their house and every time he asks for my niece my sister in law texts him if your not with me you cant have any contact with her im like wtf are you serious. My brother tried face timing my niece on her ipad and when she picked up her mother yelled say bye to your father for the last time because he is a piece of shit !! I was so freaking furious bc shes already trying to ruin their father daughter relationship though he did nothing wrong. I was nice and patient trying to talk to her and she flat out tells me that if my brother is not gonna be with her than he cant see their kid and that she will make his life a living hell. I want to beat this crazy b&$&?s ass so bad but of course i wont do anything that can harm my brother from seeing his daughter.

** He has all the text messages of everything shes saying. Shes also texting him things like i know your information like his social you know private information .
