Unfortunately lawyers can be very toxic and yet be extremely good at manipulating where they have a lot of practice at being very "convincing". Just let life itself be what finally gets this guy in the end and could actually end up punishing him in ways that cause him to suffer in ways you might never dream up yourself.

You should focus on the fact that your daughter is smart enough and strong enough to get away from this toxic man. She should not bathe in desire for revenge either, instead just work on gaining freedom from him and being able to focus on herself and regaining her life back again and that she is lucky that she has your support to do just that. You can be very wise divine, and have a lot of helpful wisdom to share with others here at PC who get stumped and need support and advice. Someone hurt you daughter, you love your daughter so it's very human to want to strike out at the person who hurt your daughter.
