That is the focus of the entire movie A Christmas Carol: Scrooge's behavior before and after his revelations from the Ghosts. Before his 'dream,' he was miserly and mean, impossible to get along with, misanthropic, cynical, and bitter. After his night with the four Ghosts, he was a changed man. He became generous, kind, outgoing, affectionate, and sensitive to others' needs, because he had been shown the ugly consequences of his selfish behavior.
