Emotional expressions of moral value

In "Moral Luck" Bernard Williams describes a lorry driver who, through no fault of his own, runs over a child, and feels "agent-regret." I believe that the driver's feeling is moral since the thought associated with this feeling is a negative moral evaluation of his action. I demonstrate that his action is not morally inadequate with respect his moral obligations. However, I show that his negative evaluation is nevertheless justified since he acted in way that does not live up to his moral values. I then use this distinctive negative moral evaluation to distinguish agent-regret from guilt and mere regret.
