Nick's future is dependent on himself, and if he loves his children or not. If it's true that his kids ratted on them to clergy/teachers, that's a hell of a lot of resentment. Rekieta either comes out understanding that he was out of control and his children had his best interests at heart, or he resents them even more than his addict brain already did prior to this incident. It's one thing if Imholte ratted on them, or some other external force.
But it's another thing altogether to accept that the "betrayal" came from inside, from his own progeny. There is no copesplaining with them. There's no cutting them off, no real way to "other" your own spawn. It's simply accept fault or become a deadbeat, those are his options. I had a mild suspicion the black eye came from one of his children actually, doesn't rekieta have an older son?
