As he lies dying Victor Frankenstein tells Walton that he no longer feels the "burning hatred and ardent desire of revenge I once expressed." Now, Frankenstein states, he only feels himself justified in seeking the death of his "adversary," the creature whom he has created. In the final chapter, he examines his past actions and behavior, and he says that he feels no guilt:
My duties towards the beings of my own species had greater claims to my attention, because they included a greater proportion of happiness or misery. Urged by this view, I refused, and I did riht in refusing to created a companion for the first creature. He showed unparalleled malignity and selfishness, in evil: he destroyed my friends; he devoted to destruction beings who possessed exquisite sensations, happiness and wisdom; nor do I know where this thirst for vengeance may end.
He rationalizes his having caused the deaths of his family and friends with a declaration that his greater obligation was to not acquiesce to the demand of the creature that he create another for him. Frankenstein feels that his only failure is in not destroying the creature he has created. Now, he asks the ship's captain to "undertake my unfinished work." Victor Frankenstein remains narrow-minded and selfish to the end.
On the other hand, when the creature discovers that Frankenstein has died, the creature boards the ship. Walton describes the creature as having
every feature and gesture ...instigated by the wildes rage of some uncontrollable passion.
'That is also my victim!' he exclaimed: 'in his murder my crimes are consummated; the miserable series of my being is wound to its close! Oh Frankenstein! generous and self-devoted being! what does it avail that I now ask thee to pardon me? I, who irretrievable destroyed thee by destroying all thou lovedst. Alas! he is cold, he cannot answer me.'
In contrast to his maker, the miserable creature continues to utter "wild and incoherent self-reproaches." He blames himself for the death of Victor Frankenstein, whom he did truly love. He retorts to the castigation of Walton, telling him that he, himself, suffered great anguish for his deeds. For instance, after the murder of Clerval he felt pity for Frankenstein, and abhorred himself. This is in contrast, also, to Frankenstein who calls the creature his "adversary."
But, even though he has felt pity, the creature admits to having become obsessed with his "demoniacal design." In this drive for the accomplishment of his plan, the creature resembles Frankenstein who, also, was driven to destroy. However, now "no guilt, no mischief, no malignity, no misery can be found comparable to mine," he declares--feelings in sharp contrast with those of Victor Frankenstein.
The creature asks Walton, "Am I to be thought the only criminal when all human kind sinned against me?" He cites Felix's having spurned him and drove his friend from his door, and "the rustic," whose child he saved. Yet, he admits to his crimes, stating that Walton's abhorrence cannot equal that with which he regards himself. He, then, turns to the body of Frankenstein and points to the great contrast between the two beings. For creatures rankles with guilt while Frankenstein felt justified in his actions; in his guilt, the creature promises to destroy himself: "Soon these bruning miseries will be extinct."
Victor's last words were more geared towards the captain. He wanted him to know not to go further North on his quest, but instead to turn South, the safer direction. He told the captain to take his brave men homeward. I believe he was facing his own losses and did not want the captain's ambitions to cost him and his men their lives such as Victor's ambitions had cost him the lives of his friends and himself.
The creature's last words were of sorrow that he had lost his father. He asks Frankenstein to pardon him for the things he had done. He is sorrowful for destroying Victor by his destruction of those Victor had loved. He expresses that he hates himself for the things that he had done and he feels his life and actions are over since Victor, his father, is gone.
