Well sometimes it can, but other times not. You see sometimes aurthurs make stories to teach morals and values other time its just to entertain. And example of a story just for entertainment is "The Three Little Pigs". There is no moral or lesson in this story (unless you consider "Blowing at a brick house won't blow it down a moral of course) however the story of little red riding hood does have a moral. The moral of this book is "Never follow strangers" or stranger danger like our parents say. So to answer the question it just depends on the story.
( please forgive me if there are irrors my spelling isn't the best)
