Hopefully they will delve more into this path. Of course forgiveness for abuse isn't and should be easily achieved, if ever, especially child abuse.
He is barely a step below that via child negligence. But that doesn't excuse anything.
He should have been more proactive, and he didn't, and I do hope they delve into his realisation of that fact and how he will try to work for making their life better.
Not forgiveness, since a parent like this doesn't deserve it, but to make their life as rich and happy as they can be
without expecting forgiveness (and later on, it is their, the children's prerogative whether they can see it in themselves to forgive him, or at least make amends)
