Who is scrooge?
Scrooge is Ebeneezer Scrooge, the protagonist of Dickens' tale. He is Bob Cratchit's boss and drives him hard and mercilessly, unable to see the great devotion and hard work that Bob puts in, only able to consider what he might save by pushing him harder and paying him less. It is his great miserliness that forms the basis for the conflict of the story as he is, at the outset, unable to feel any joy of giving or holiday spirit.
As he entertains the ghosts of Christmas past, present and future he regains his ability to feel the joy of the season and reconciles himself by rejoicing in sharing the holiday cheer and his wealth with Bob and others around him.
