Dark Romantic writers sometimes focused on the psychological effects of sin. Tom experiences some psychological distress after making his deal with
the devil. How does Tom suffer psychologically from his sin?

He suffers from the sin he committed with the constant fear of being condemned to hell after his death.

Explanation:

He suffers from the sin he committed with the constant fear of being condemned to hell after his death. This thought terrifies Tom and takes away all the peace and quiet, because he is very afraid. This makes him desperately look for a church and become a religious fanatic to the point of looking like a madman, begging for his religiosity to save him, but he doesn't get that grace.

the excerpt from chapter 2 of "animal farm", by george orwell that is an example of foreshadowing is "these three (snowball, napoleon, and squealer) had elaborated old major's teachings into a complete system of thought to which they gave the name of animalism." animal farm is an allegory of how czarist russia developed into communist russia with all its corruption. old major's teachings represent marx's theories turned into communism, animalism, by the three pigs. this foreshadows the oppression and corruption that will follow this revolt.
