Still below angels, but above normal men, are heroes. Traditionally these are people who do the right thing at great personal sacrifice. The Greek heres means protector or defender. Sometimes protectors must do bad things for the greater good. Knights, at least as a mythic ideal, strove to be as close to angels as humans could be. In the later Middle Ages, the angelic ideal of chivalry was democratized as the bourgeois sought to raise their children according to gentlemanly rules of honor, too. Even as the chivalric code evolved, the idea of heroism remained largely intact. Heroes make sacrifices for the greater good.
