Sergeant-Major Morris fears for the curiosity and human greed displayed by the White family, in addition to fearing for what may happen to their next owner.
Explanation:
The book "The monkey's paw" is a novel of the genre of horror literature, published in 1902, it tells how Sergeant-Major Morris gets a stuffed monkey leg that was haunted and fulfills 3 wishes to 3 different owners, and that its current owner's wishes are fulfilled but in a counterproductive way.
The White family shows some interest in buying the monkey paw, but Sergeant Morris does not want to sell the monkey paw because he fears what may happen to its next owner due to a desire for a fast path to a life of tranquility and luxury.
I believe that the first and last paragraphs are realism because of their cynical descriptions of harsh things, and the middle two are romanticism because of their embellished/elegant descriptions.
