If we based it on the given situation above regarding a protagonist who grew up witnessing the dark side of human nature, I would say that the best setting an author would use is option B: <span> A small town in the South during the 1950s where racism is common. Hope this helps.</span>
Keep in mind that Frankenstein is the guy that created a monster out of corpses, not the monster. After he had ascended to the summit of Montanvert, <span>Frankenstein meets the monster. </span>
