There is always shooting them, or like in the old west when someone needed a killing, tie the foot into the stirrup with the guy on the ground and let the horse run for a bout a mile..whuppin takes too much energy. I don’t remember which Clint Eastwood movie it was but he had a piece of straw in his mouth and says Some people just need a killin.. Bang bang..
“It’s a hell of a thing, killin’ a man, you take away all he’s got and all he’s ever gonna have.” ~ Clint Eastwood, Unfogiven
And you save anyone and anything else he’s going to kill in the future!
