But he has no interest in being responsible in most facets of his life - lazy, dishonest, drop out, slovenly. In a sense too old to be acting the way he does, and too immature to be playing house with a woman with a child. Bianca being apparently not too bright herself, and also an unacceptable ethnicity for the clan. So he is like Tony - taking the easy way and not willing to work. Clearly he is in line for falling into la cosa nostra.
I'd bet he's in line for trying to fall into la cosa nostra but instead inviting terrible tragedy. AJ has absorbed the lesson of his parents' example, not their words. He is utterly uninterested in making an honest living since he never had that as an example in his life. He was basically intimiditated with violence into working the construction job. This after being fired from Blockbuster for stealing and selling stand-up posters and, like his parents might, rationalizing that he's helping the environment.
But I agree with FOMW that he has not developed the necessary temperament for it. He's more like Fredo than any other character I'd say.
Keep in mind, AJ was not really going to kill Junior for revenge. He thought, consciously or not, he'd impress his dad with his manhood and be taken into the family business. Yet he Fredoed the job in the end. The heart to heart AJ and Tony had after that is already not taking. Just like no one else around him is able to resist "The Life" either and its attendant sex, respect, excitement. He doesn't want to make an honest living any more than Tony does. It's the same thing that drove Jackie Jr, Matthew Bevilaqua (and maybe the actor who plays him in real life). And I predict it will end up no less catastrophically for AJ.
