Scrooge is the main character in A Christmas Carol. He is portrayed in the beginning of the story as a misanthropic and avaritious miser, who has no care for the wellbeing of anyone, and is obsessed purely with collecting money. However, he has no interest in spending any of this money, often limiting himself to the most basic needs (like eating gruel). However, after being visited by the ghost of his dead business partner Jacob Marley, he is visited by three more ghosts, who between the three of them push Scrooge to redeem himself from his poor ways.
Scrooge is a caricature of the Victorian industrial middle class. Dickens presents him as a caricature of the middle class to appeal to them and criticize their attitudes indirectly. By using the idea of redemption at the end of the novella, he creates a message that if Scrooge, the worst of the worst of the IMC can change, so can every member of the IMC. He is a strong supporter of Malthusian theory, echoes in his reasonings for not giving money to the charity workers who visit him.
