That situation, for me, was Vietnam. I was drafted, and I felt some obligation toward that service, but to me, now and then, killing and war is morally wrong. So I became a conscientious objector. If it had been world war 2, I might have gone, despite my moral qualms, because the danger was clear and present and unmistakable. I would likely have been a medic, a non combatant, but the evil nature and intentions of the enemy were so clear, I would have felt obligated to play some part. But in Vietnam, in Iraq, the war, to me, above and beyond my moral objections, is wrong ethically and morally. Wars fought for all the wrong reasons which should not ever have been fought.
