Villains are staples of stories for kids. Making them bigger, meaner, madder, more impossible to defeat — that's how you build the ideas of fear and then, inevitably, of courage. A small person faces a giant, or a witch, or a wolf, or Jafar, or Cruella De Vil, or the Buy 'N' Large, and by watching that happen, you learn. You learn what it takes to beat the bad guy. You learn that you, too, can beat the bad guy. You learn not to lose heart and not to give up. You use something inside yourself to beat something outside yourself.
