Who is the guy? Is he connected? Does he deal for another family, or maybe another wiseguy in the same family that you're trying to get in with...is somebody getting paid by him on a regular basis, and would not be happy to lose that income.

Anybody can kill anybody. You don't automatically get respect just for pulling a trigger. You have to be smart, and always remember that it almost always comes down to money. Plus you need to follow rules, and play politics. That's just the way it is.
