If means, motive and opportunity are present, the answer to your question is the whole point of returning fire or at least engaging a deadly threat.
Someone points a gun at me, if I don’t act appropriately I can assume I’m a dead man! Someone points a gun at anyone in my vicinity, I can safely say the gun is intended to do grave bodily harm or death.
Maybe we could ask every person who died at the hands of a bad guy with a gun!
Don’t misunderstand, the last shot taken, was an emotional one, or since we were not there, maybe the body moved in a threatening manner.
Additionally I’m not sure you want to be asking yourself that question when you’re looking down the barrel of a gun in the hands of someone unstable enough to rob people in an aggravated manner.
