Remorse for doing his job?

Hiroshima and Nagasaki each suffered the effects of an atomic bomb. As a result of the bombs being dropped, Hirohito chose to intervene against his own military council and ended the war. The bombs were devastating, yet they didn't do as much damage as had the fire bombing of Tokyo. It was a new type of bomb that caused Japan to see that they could not win. Their only course was suicide or surrender. Sixty years have passed since those bombs were dropped and none have been used in war since then. On the NBC news coverage of the event, Brian Williams asked the pilot of the Enola Gay, the plane carrying the bomb to Hiroshima, if he had any remorse for dropping the bomb. The response? "No, I was doing my job to try to end the war." We were being faced with the strong possibility of horrific casualties on both sides by invading any of the Japanese home islands. How come we have come to the point that many of the people of this country are sorry or remorseful for using a specific weapon? What makes them feel that a rifle with a bayonet is preferable to an atomic bomb? What makes them think that ending a war with more casualties on the enemies side is not a good idea? I realize that there were some awful pictures of the destruction both of people and the cities. This may have helped to keep us from using these weapons again, but I don't think that using them to end a terrible war with Japan was wrong or that we should feel remorse for using them.
