I once heard someone telling his friend the story of the Boy who cried Wolf!, with the obvious conclusions about lying. In a surprising twist, his friend disagreed – the moral of the story, he countered, was obviously a different one: never to be caught in the same lie twice.
Instead of re-interpreting a known tale, I sometimes think how much better a tale could be if it ended differently.
The bible recounts the story where God commands Abraham to sacrifice his son. Priests praise this story as an example of complete Faith in the moral superiority of God.
What an opportunity missed. In a morally superior version of this story, Abraham would have told God to screw himself.
