Not a Villain in the Bunch

   

 This Friday at my Child Development Center we celebrated "Fall Festival". The children were encouraged to dress as superheroes, princesses, or a person from a storybook. No pirates, no skeletons, no Captain Hooks, and we were not allowed to mention Halloween. Like as if the kids didn't know it was Halloween.
     How can we have all good guys and no bad guys? Can children fully understand what not to be like? All children's folktales have bad guys, usually a wolf, and sometimes it's stepparents. I put this question out for opinions of my classmates--is it wrong to let children dress up as the big, bad wolf, or the wicked witch?
