Looking for advice

So I've been in mental warfare for quite some time fighting abuse and I would to know any advice on responding to an evil mother who causes tension in the family. I mean the one who comes home, sighs, always gossips, lies, and cause siblings to hate one another. One who constantly blamed the father for every mistake, is never wrong, uses you then throws you aside, and will not talk to you with throwing in an insult or two. One who lives 247 for any opening they can find to fight someone or argue as the father is used constantly as a slave to do her bidding so if he tries to reason all she has to do is scream help or play the victim. One who teaches their own daughters to treat men they way she does, blesses her, and praises her the more she does while sabotaging their futures. The alienated father is too scared to fight and sells out anyone who chooses to help for the sake of fake satisfaction and offers presented by the mother which lasts for a small moment as he is swiped back into doing her dirty work. One who scapegoats those who live for the truth and drounches the other in gold. What do y'all think? Any advice?
