More spoilers! Just to prove that you can't stop thinking about The Sopranos, there was one other issue I meant to discuss in my prior post but did not. As much as Tony's two families create risks, stresses, and threats, there is a difference between them and, in the end, it seems, Tony prefers his biological one. There was a clear parallel drawn between Tony's reaction when confronted with life threatening situations involving Christopher, his mafia "son," and AJ, his biological son. In the former, Tony became hyper-rational, recognizing that he could remove a threat at no risk to himself; in the latter, as much as he is frustrated with AJ and would, in some ways, be better off without him, he did what almost any father would do, saving him. He could have quite easily had AJ suffocate with no one knowing, but he did the right thing. Just shows there is still a little bit of humanity in him.
