There is nothing to admire, they live a pretty shitty life even tough some of them gain a lot of money and some bonuses in their life from it. A lot of them just didn't see another way in life than turning to crime so they followed it up. It doesn't matter if it's just the Italian mobsters or gang members nowdays. Running a life of crime has it's costs and it's big. Just think of how many of them got killed, because of some mistake they made or because someone just decided to take over. How many of them got snitched out to the authorities and are now doing time for rest of their lives. Then on the other side it's the stress of it all combined, if you'll do everything right or will you get killed tomorrow. I don't wonder why they all got cancer, stress just kills you..
