The Cat And The Rooster

     One day a cat happen to grab hold of rooster for its evening meal. She wanted, however, a good excuse for killing the bird.

 "I need to rid the world of you," she told the rooster, "You constantly make your horrible noises throughout the night, interfering with men's much needed sleep. The world will be better off without you."
     "No," said the rooster, "I crow for the good of men. I wake them up each morning when it is time for them to start work for the day, so that they may earn their living."
     "Ridiculous!" said the cat, and she ate him.

   

       

Evil is determined on doing wrong even when it hides behind the disguise of fairness.
