I didn't say their only purpose is to kill. My initial response was just to your story about privates pushing that guy down the stairs. You offered that charming little tale and alluded to the military to begin with, I assumed that incident didn't directly involve anyone in a leadership position, but if so that hardly weakens my argument. My point was there are parallels as to why people join and the type of people you find in either discipline, nothing more. I don't know anything about being a gangster either, I find it about as interesting as the military.
