I agree with everything you said, however, there's another aspect to this that's even worse.
Chris doesn't care about that stuff because he knows there's no punishment involved. In fact, after fucking Barb, his life got easier since he had zero bills, he hasn't had to clean or do "adult stuff", and hell, he doesn't even have to buy food anymore unless it's candy and shit. Not only has jail helped Chris to not "adult" anymore, but they removed a good deal of his "stressors" that he dealt with.
And... after two years, they just aren't cutting him loose, they're even providing more stuff so Chris can put off adulting. I wonder if, Chris refusing to learn or do anything will just keep him in these programs longer, if that's the case, then not only will he get his tardbux, which won't be needed to go towards living like a normal person, but the system will just expend more resources to keep him inside.
Chris is probably coming out of this smelling like roses, and won't have the attitude that doing something monstrously horrible is "wrong" because "jail wasn't such a scary place". So unless he fucks up and gets to go to actual prison, this is probably the best few years Chris has ever had since he hasn't had to do much of anything. I have a feeling he didn't even say he was sorry or show remorse.
