seems to me like you have two issues here:
you wanting your daughter to have a father in her life;
you wanting him out of your life.
That's a lot of difficult conflicting emotions to work through, especially if you're seeing him around with his new friend.
I get that I have NO CONTROL over what he does and wishing for it will drive me crazyIf he's an out and out psycopath he will have no respect or compliance with rules or the law. That's the extreme end of the spectrum and I guess most people who're like that spend time in prison before too long.
Some narcissistic people see legal boundaries and won't break the law ( I know my ex wouldn't defy a court order and compromise himself ) so it could be a way for you to control things to some extent.
But some narcissists ( and non-narcissists ) thrive on the attention too of going in and out of Court and acting out in public.
I haven't read much of this but I agree with what I've seen so far

I will also add
there is some really bad advice on the internet about the topic 'divorcing a narcissist', especially someone prone to violence. Any advice which tells you some simple behaviour of your own can control or change the N's behaviour ( especially by losing your cool or getting abusive or violent yourself ) is more likely to make you look bad or could be dangerous.
During my marriage if I ever lost my temper with my husband ( by which I mean uncontrolled shouting and anger outburt- which was surprisingly rare given the provocation ) he would react by instantaneously and uncontrollably hitting out/ throwing something. I'm not even sure it was about N, he just couldn't handle my aggression directed at him. I was hit several times over the years before I worked it out, and he went to therapy.
I have found that there is no simple solution to any of this- and my way of dealing was loads of therapy myself. Find what's healthy and stick to it like a broken record. As I got healthier a lot of it has changed the whole family dynamics and we can all communicate better than ever despite the Nism. I didn't want to leave one unhealthy life behind and move onto another- I knew I had to work out my place in all this, why I was choosing N partners, end the relationship with kindness and forgiveness I suppose. But I was angry, confused, bitter. And jumped right into a new relationship with a man who was totally pathological- worse than my ex! I couldn't do it myself, I needed therapy.
PPS. the other factor is time- I sometimes think there should be a 'pre-divorce' where people work their emotions out and start to heal before they go into a situation where their feelings are going to affect important decision-making. It's definitely been a lot easier for us to remain married for the first two years of our separation and work out the problems together as a family. When we do divorce it will be a mutual decision based on what is best for our son and ourselves, and it won't involve lawyers 'taking sides' and encouraging anything underhand or unpleasant.
