What does the monster plan to end his life and what does he say in his farewell speach?

The creature ruefully remarks that he did not expect to find any sympathy from Walton, but is content to suffer alone. He cannot believe that he is the same being who once dreamed of sublime beauty and transcendent goodness; now he is "the fallen angel become a malignant devil." He wonders why Walton does not despise Felix, or the rustic who sought to kill the savior of his child; the monster feels himself to be "an abortion, to be spurned at, and kicked, and trampled on." Walton's hatred of the creature cannot, however, equal the creature's hatred of himself; the creature says that he will throw himself upon a funeral pyre, and thus be saved from the enormity of his remorse. With that, he leaves the ship, and is "lost in darkness and distance."
