What ultimately happens to Gulliver's view of humanity by the end of the narrative?

By the end of "Gulliver's Travels," Gulliver's perspective on humanity transforms significantly, leading him to a profound distaste for human nature. His journey through various fantastical lands exposes him to different societies, including the rational and noble Houyhnbnms, which starkly contrasts with human behavior. Observing human vice, corruption, and pettiness, Gulliver becomes increasingly disillusioned with mankind. He concludes that humans are driven by base instincts and are frequently incapable of rational thought or virtuous behavior.

This culmination of experiences leads Gulliver to thoroughly detest humanity, marking a shift from an initial curiosity and criticism to outright disdain. His ultimate decision to isolate himself from humans, preferring instead the company of horses, encapsulates his rejection of human society. Thus, he criticizes the very essence of humanity, having lost hope in its potential for redemption or improvement, aligning with the interpretation of a complete loathing of human beings.
