I see a hero as one who volunteers to take a personal risk on behalf of his or her group/tribe/country. Whether or not the risk results in death or injury does not have a bearing on whether or not the actions taken were heroic. If one is conscripted against one’s will and dies in battle one is not a hero, but more like an unlucky slave. Also, the label is bestowed by the group that stands to benefit from the hero’s actions—your hero in warfare is my evil opponent.
