It's foolish for the pure utilitarian to leave the human factor out of the equation. Or perhaps his error is to consider dollars to be the ultimate commodity. Really, we as humans work for a much more valuable commodity than money. The fighting of the war in the first place is a human attempt at creating a good story (of a country that actually realizes peace and prosperity). The saving of one man (whether soldier or civilian) is yet another attempt at such a story. It's the human way.
