That's the biggest myth of all: That you have to kill someone to get made. Even in the "old days," there were plenty of made guys who never pulled the trigger. The rule is that you have to be WILLING to kill for the family. Nothing more, nothing less.

Besides, even if you are in on a hit, it doesn't necessarily mean that you pulled the trigger yourself. You may have been in on the planning, or driven the crash car, or functioned as a lookout. But this is a topic that's been discussed here ad nauseam. Try the search feature. It's a great tool.

As far as the original question, has anyone become boss without hitting someone? It's possible. Especially today.
