with what is Walton obsessed in the "Frankenstein"?

Question

i think is finding the passage to the East but not sure if right or not.

Answer 1

Robert Walton: Indirect narrator of the story, he tells Victor Frankenstein's story through letters to his sister, Margaret Saville. Walton is a self-educated man who set out to reach and explore the North Pole and find an Arctic passage to connect the Atlantic and Pacific Oceans. While his ship is locked in ice, his crew sees Frankenstein's monster pass by on a dog sled and Frankenstein himself, exhausted and weakened, not far behind. They take Frankenstein aboard and Walton nurses him and talks with him because he has been longing for a friend. In seeing Walton's raw ambition to explore the North Pole at all costs, Frankenstein is prompted to tell the story of his destruction that a similar ambition brought upon him. After Frankenstein's death and just before the ship heads back to England, Walton is also the last to see the monster before he goes north to kill himself.
