How is what the reader learns about human nature different from what Gulliver learns?

The reader learns that human nature is often flawed, marked by hypocrisy, greed, and a tendency toward conflict, as depicted through the various societies Gulliver encounters. In contrast, Gulliver's perspective evolves to become increasingly cynical and disillusioned, leading him to view humanity as inherently corrupt and base. While the reader may understand these flaws with a degree of detachment, Gulliver's experiences ultimately drive him to a deep-seated misanthropy, isolating him from the very nature of humanity he once sought to understand. Thus, the reader gains insight, while Gulliver's journey results in despair.
