I am now fully confident that Nick is irredeemable. There is nothing that speaks to his conscience, that aspect of him is necrotized. He could be filming CSAM or defrauding the elderly and nothing would make him question his actions if he deemed that they are proper. Nick is below Ralph, not just because the mistreatment of the kids is worse, but because Nick isn't even able to fake remorse for the public, Nick is incapable of admitting guilt even when not doing so is financial or optical suicide.
It should have been obvious to me when he refused to settle the Monti case out of court, but I for some reason attributed that to his vindictive personality: "Nick realises he fucked up, but doesn't want to loose face in the eyes of lawtube, so he would take the hit on the money".
Not even close as it turns out. The religion allergy fits neatly into the worldview of a hypernarcissist, so are the other instances from the gallery of copes he has for himself. No being or institution (however righteous it may claim to be) can be above Nick.
All I can say is that if he ever gets sent behind bars (the possibility of which is becoming more and more likely), he'll experience one hell of a personality break. Rekieta, there would be no mods to sweep the demons out of your head on those long grey nights.
