Maybe the hawk was an idiot for going that close to flying golfballs. Why blame the man?
I doubt the golfballs were flying past the tree when the hawk landed there. Blame the man because he, of his own volition, repeatedly took all actions necessary to create the situation whereby the hawk died.
Maybe the golf course designers should have just cut down all the trees when they bulldozed all of those acres to make a lawn for this yahoo to golf on.
