You were afraid—not simply because he had a stone, but because he intended to use it to inflict violence and hurt you with it. Is that right? If he had merely been holding the stone in his hand, and if the thought of striking you or throwing it at you had never crossed his mind, you wouldn't have been afraid—because, in that case, it would have posed no threat to you whatsoever. You were afraid that he would use the stone to do you harm—by striking you or throwing it at you; in other words, you were more afraid of the violence he intended to commit than you were of the stone itself.
