It is the spread of the good things that vindicates the whole reason we live our lives in networks. If I was always violent to you or gave you germs, you would cut the ties to me and the network would disintegrate. In a deep and fundamental way, networks are connected to goodness, and goodness is required for networks to emerge and spread.
Sometimes, violent details have been eliminated from fairy tales simply because they were deemed too graphic. So one does not, at the end of Disney's version of 'Cinderella,' see the stepsisters' eyes get pecked and pecked by doves, because Disney wanted to market the story for wholesome family viewing.
My favorite - my very favorite movie, which I suppose is a bit of a guilty pleasure in that it's like, you know, every scene, you know, pushes every button, is 'True Romance' directed by Tony Scott with Patricia Arquette and Christian Slater, and it's a fantastic, fantastic film, very violent, very romantic.
