how does the change in narration to the creature's POV affect the reading of the novel?

I don't know anyone who hasn't felt compassion, pity, and sympathy for the creature once they reach this point in the novel....... you'd have to be pretty hard hearted not to empathize with the situation that the monster is in, no matter what type of revulsion he inspires. This is the moment the creature becomes human to the reader; he's an intelligent, feeling, and emotional being. He did not ask for his circumstances........ he just wants to stop being lonely.
