What punishment has Marley received due to his actions in life?

In Charles Dickens' "A Christmas Carol," Marley is condemned to wander the Earth in chains as punishment for his greedy and selfish actions during his life. He is burdened with heavy chains made of cash boxes, ledgers, and other symbols of his avarice, serving as a warning to Scrooge. Marley’s ghost appears to Scrooge to urge him to change his ways and avoid a similar fate. His punishment reflects the consequences of a life lived without compassion or generosity.
