Why Is Modern Pop Culture So Obsessed With Battles Between Good And Evil?

In old folktales, no one fights for values. Individual stories might show the virtues of honesty or hospitality, but there’s no agreement among folktales about which actions are good or bad. When characters get their comeuppance for disobeying advice, for example, there is likely another similar story in which the protagonist survives only because he disobeys advice. Defending a consistent set of values is so central to the logic of newer plots that the stories themselves are often reshaped to create values for characters such as Thor and Loki – who in the 16th-century Icelandic Eddahad personalities rather than consistent moral orientations.
