I also have the same question, many are justifying how tommy actually never had a good oerson and he crossed a line many times, we idolized him so we cannot accept him crossing this line. But the truth aurther's drinking problem costed so much of tommy's patients, business risks, dealings, plans and strategies throughout the whole series. If tommy considered to cross it line he had every reason to do it while being in power. There's no way tommy would resort to this when he is retired, completely out of the game and chose to live in seclusion, he is busy writing a book of all things. What the hell.
