Throughout the novel, we experience the many difficulties that Victor goes through in order to create his creature, as well as the many tragedies he goes through after bringing him to life. We experience the deaths of his loved family and friends, and we experience the regret and hatred he feels towards his creation, that he was once so excited to bring into life.
When Victor Frankenstein and his monster meet in the mountains, the monster asks Victor to make him a female companion. The quote “For the first time, also, I felt what the duties of a creator towards his creature were, and that I ought to render him happy before I complained of his wickedness. These motives urged me to comply with his demand” (Shelley 85) demonstrates Victor’s understanding of his responsibility as the monster’s creator.
Though Victor Frankenstein understands his responsibility to the monster and has agreed to make him a companion, after comprehending the possible outcomes of bringing another monster to life, he destroys his progress. Now he feels it would be best for the world if he did not make another monster, after seeing the destruction that has already been caused.
Having lost everyone he has ever loved, Victor was determined to spend the rest of his life pursuing the creature. He reported that his state of mind was one of extreme agitation and that he was propelled into action out of pure revenge. “And now my wanderings begun, which are to cease but with life.... But revenge kept me alive; I dared not to die and live my adversary in being.” (Shelley 89) For some time, the creator pursues his creation; he had chased him as far as the Arctic Circle when Walton rescued him.
To sum up, Victor feels he has the right to take the life of his monster because he realizes his responsibility as the monster’s creator. Additionally, Victor’s hatred and the desire for avenge his loved ones drive him to kill the monster.
