I guess when you chokehold someone you have the power to take his life away. Or hers depending whom the chokeholdee is.
Who wants to give up THAT power? It is the ultimate aphrodisiac isn't it? Who wouldn't get off on the thought that tightening the hold can cut off all air and then well the cholkeholdee falls limp dead? I can see that would be a very hard power to relinquish. What else could you use the arm for then? Oh right shooting a gun. That will kill someone. Preferably in the back as he is running away and very preferably someone without any weapon to strengthen the odds of the shooter surviving. Sure. Why not? What could it hurt? Everybody says so. In a "certain" period of time. That I can tell you.
