Question

in this excerpt from a christmas carol by charles dickens, which set of lines show that scrooge is becoming aware of his own unfeeling attitude and behavior?
\what do you call wasting of it?\ asked old joe.
\putting it on him to be buried in, to be sure,\ replied the woman with a laugh. \somebody was fool enough to do it, but i took it off again. its likely aint good enough for such a purpose, it isnt good enough for anything; its quite as becoming to the body. he cant look uglier than he did in that one!\
scrooge listened to this dialogue in horror. as they sat grouped about their spoil, in the scanty light afforded by the old mans lamp, he viewed them with a detestation and disgust, which could hardly have been greater, though they had been obscene demons, marketing the corpse itself!
\ha, ha!\ laughed the same woman, when old joe, producing a flannel bag with money in it, told out their several gains upon the ground. \this is the end of it, you see! he frightened every one away from him when he was alive, to profit us when he was dead! ha, ha, ha!\
\spirit!\ said scrooge, shuddering from head to foot. \i see, i see. the case of this unhappy man might be my own. my life tends that way now.\
merciful heaven, what is this?
he recoiled in terror, for the scene had changed, and, before him, there lay a something covered up, which, though it was dark, announced itself in awful language.

Explanation:

The lines show Scrooge realizing the parallels between his own cold, unfeeling treatment of others and the way the characters speak about the dead man, triggering his terror and self-awareness.

Answer:

"Spirit!" said Scrooge, shuddering from head to foot. "I see, I see. The case of this unhappy man might be my own. My life tends that way now. Merciful Heaven, what is this?"
