*Killing Christopher was likely his biggest mistake of them all. Say what you will about the drug issue but Christopher is the only one left at the end of the show had Tony not killed him. One would imagine he would have been active during the war with NY. It's hard to thing Carlo could have indicated Chrissy in the information he has informed considering the separation between Tony and Chris in business ventures to maximize total net gain while keeping each other's exposure minimal as possible. If Chris doesn't die in the war w/ NY, (IMO he's the most important guy to protect on the Jersey faction in that war due to youth/earning capability) he is likely running the show not long after the war. Bobby dead, Sil a vegetable, Carlo informing, Tony dead or indicted, Patsy either jumped ship NY or indicted. Who is left in that scenario to lead but a few key guys. Chrissy, Paulie, Benny. Food for thought...
I think Tony killing Chris wasn't a mistake. The mistake was giving him power and setting him up for future leadership. Chris was not a leader. The only thing he had going for him was being Tony's nephew. Outside of that how much respect did he gain on his own? He ended up a junkie, and his former fiance ended up being a rat.
Once Tony knew Chris couldn't get clean and would be a liability going forward, in that life killing him was a good 'business' decision.
