"In the midst of martial conflict it is a soldier's duty, clad in his helmet, to thirst for blood, to concentrate on killing, to plead his case with his sword alone, to show himself in all his actions an unyeilding warrior, displaying ferocity more than ordinarily brutal. But by the same token, when the turmoil of battle is over and he laid aside his arms, ferocity too should be laid aside, a humane code of behavior should be once more adopted..."
