Final answer:
The narrator criticizes Tom and his wife in 'The Devil and Tom Walker,' highlighting their greed and corrupt morals through satire and irony.
Step-by-step explanation:
The narrator's attitude toward Tom and his wife in “The Devil and Tom Walker” is one of clear contempt and criticism. Washington Irving sketches characters that are morally corrupt and avaricious. Tom Walker is depicted as a miserly, selfish man who eventually makes a deal with the devil, demonstrating his ultimate moral decay. His wife, similarly, is presented as an abusive and equally greedy person. The narrator uses irony and satire to critique their behaviors, making it evident that he views both characters unfavorably.
