Well keeping his kids with him just means more shit stain kids and eventual adults 9 times out of 10.
You don't keep abusive fuckers with their children. That's good damn common sense 101.
Assuming the wife's any better which frankly is unlikely. Good chance the kids are just goanna grow up to be racist bigots.
And if they don't fucking damn lucky for humanity. Abusive households just put out abusive people much of the time.
