Why was scrooge afraid of the 3rd ghost but not the other two?

Scrooge was afraid of the third ghost, the Ghost of Christmas Yet to Come, because it represented an uncertain and grim future, showing him the consequences of his actions without the hope of redemption. Unlike the other two spirits, who offered insight and opportunities for change, the third ghost was silent and ominous, presenting a bleak vision of death and loneliness that deeply unsettled him. This fear stemmed from his realization that he might die forgotten and unloved, which starkly contrasted with the more instructive and reflective nature of the first two ghosts.
