And now my wanderings began, which are to cease but with my life.

As he nears the end of his story in Chapter 24, Victor explains to Walton that after the deaths of everyone dear to him he made the decision to leave behind his home in Geneva forever and to commit the rest of his life to find and destroy the monster he created.

Never will I give up my search until he or I perish; and then with what ecstasy shall I join my Elizabeth and my departed friends.

In Chapter 24, Victor continues describing how committed he is to finding and killing his creation. He tells Walton that the monster sometimes leaves him taunting clues, etched into the barks of trees or inscribed on rocks, but that this only strengthens his determination to destroy him. Though he yearns for the afterlife because it will reunite him with Elizabeth and his other lost loved ones, he swears that only his death or the the death of the creature will end his quest. (Interestingly, the monster will speculate about the afterlife with his final words at the end of the book.)
