What should be the other ending than the ending which happens in the novel Christmas carol?

Answer 1

The "other ending" based on what Scrooge was shown by the final spirit was his own death and the lack of care by others that he had died. In deed many people would be seen to be happy that the miser had gone

Answer 2

One alternative ending for "A Christmas Carol" could be that Scrooge does not ultimately change his ways and continues to live his life in greed and selfishness. This would result in a darker and more pessimistic conclusion, emphasizing the consequences of not embracing the spirit of giving and compassion.
