Charles Dickens wrote A Christmas Carol to highlight the importance of compassion, kindness, and generosity during the holiday season. He was deeply concerned about the growing divide between the wealthy and the poor in Victorian England, and he wanted to remind people of the true meaning of Christmas. He also wanted to encourage people to be more charitable and generous, and to show the importance of friendship and family relationships. He hoped that his story would inspire people to be more caring and thoughtful during the holidays.
