Yep. That's just what I would want to do at 53. Become a daddy all over again! Your sympathies are rightly placed. Feel compassion for the child.
My XH makes me angry also with the way he treats our boys. (He thinks he's the freakin father of the year.) Ultimately, we have no control over the choices they make regarding our children. Just know that there will be a time of accountability. There always is, eventually.
I have moved down the road of acceptance, but I too still get angry about the way everything worked out. I sometimes think that it will take my XH waking up and owning all of the crap that he did before I will really be able to release it. Probably better not hold my breath on that one.
Thanks for sharing your perspective. It's nice to hear about people who are a little further down the road on this journey.
Have a good day.
