Final answer:
Robert Walton is a character in 'Frankenstein' with a thirst for knowledge, similar to Victor Frankenstein. Victor's cautionary statement to Walton hints at the dangers of achieving one's desires without foresight, which is a central theme in the novel.
Step-by-step explanation:
Robert Walton serves as the narrative frame for Mary Shelley's Frankenstein. Walton is a sea captain on an exploratory mission to the Arctic, seeking knowledge and adventure, much like Victor Frankenstein pursues scientific discovery without considering the consequences. Walton's character parallels Victor in ambition and the thirst for glory, highlighting themes of hubris and the pursuit of knowledge in the novel. When Victor warns Walton that 'gratification of your wishes may not be a serpent to sting you, as mine has been,' he alludes to the biblical serpent and implies that the pursuit and attainment of one's desires can lead to unforeseen suffering. This reflects Victor's regret over creating the monster, which brought him unimaginable grief instead of the satisfaction he anticipated.
