Explain why the man agrees to tell Walton his story.

Walton begins to share his feelings with the man, and he attempts to convince him that things can change... that fate can lead one in different directions. Victor explains....

"I thank you," he replied, "for your sympathy, but it is useless; my fate is nearly fulfilled. I wait but for one event, and then I shall repose in peace. I understand your feeling," continued he, perceiving that I wished to interrupt him; "but you are mistaken, my friend, if thus you will allow me to name you; nothing can alter my destiny; listen to my history, and you will perceive how irrevocably it is determined."
