What happened when Sroorge saw the uncared and unwatched body of a man?

Scrooge realized that the unwatched and uncared for man was very like himself.. He understood that like this man, there was no one who cared whether he lived or died.

No voice pronounced these words in Scrooge's ears, and yet he heard them when he looked upon the bed. He thought, if this man could be raised up now, what would be his foremost thoughts? Avarice, hard dealing, griping cares? They have brought him to a rich end, truly!

He lay in the dark, empty house, with not a man, a woman, or a child to say he was kind to me in this or that, and for the memory of one kind word I will be kind to him. A cat was tearing at the door, and there was a sound of gnawing rats beneath the hearthstone. What theywanted in the room of death, and why they were so restless and disturbed, Scrooge did not dare to think.

'Spirit!' he said, 'this is a fearful place. Inleaving it, I shall not leave its lesson, trust me. Let us go!'
