Conclusion
Frankenstein builds the creature in the attic of his boarding house in Ingolstadt after discovering a scientific principle which allows him to create life from non-living matter. Frankenstein is disgusted by his creation, however, and flees from it in horror. Frightened, and unaware of his own identity, the monster wanders through the wilderness.
He finds solace beside a remote cottage inhabited by an older, blind man and his two children. Eavesdropping, the creature familiarizes himself with their lives and learns to speak, whereby he becomes an eloquent, educated, and well-mannered individual. During this time, he also finds Frankenstein's journal in the pocket of the jacket he found in the laboratory and learns how he was created. The creature eventually introduces himself to the family's blind father, who treats him with kindness. When the rest of the family returns, however, they are frightened of him and drive him away. Enraged, the creature feels that humankind is his enemy and begins to hate his creator for abandoning him. However, although he despises Frankenstein, he sets out to find him, believing that he is the only person who will help him. On his journey, the creature rescues a young girl from a river but is shot in the shoulder by the child's father, believing the creature intended to harm his child. Enraged by this final act of cruelty, the creature swears revenge on humankind for the suffering they have caused him. He seeks revenge against his creator in particular for leaving him alone in a world where he is hated. Using the information in Frankenstein's notes, the creature resolves to find him.
The monster kills Victor's younger brother William upon learning of the boy's relation to his creator and makes it appear as if Justine Moritz, a young woman who lives with the Frankensteins, is responsible. When Frankenstein retreats to the Alps, the monster approaches him at the summit, recounts his experiences, and asks his creator to build him a female mate. He promises, in return, to disappear with his mate and never trouble humankind again, but threatens to destroy everything Frankenstein holds dear should he fail or refuse. Frankenstein agrees, and eventually constructs a female creature on a remote island in Orkney, but aghast at the possibility of creating a race of monsters, destroys the female creature before it is complete. Horrified and enraged, the creature immediately appears, and gives Frankenstein a final threat: "I will be with you on your wedding night."
After leaving his creator, the creature goes on to kill Victor's best friend, Henry Clerval, and later kills Frankenstein's bride, Elizabeth Lavenza, on their wedding night, whereupon Frankenstein's father dies of grief. With nothing left to live for but revenge, Frankenstein dedicates himself to destroying his creation, and the creature goads him into pursuing him north, through Scandinavia and into Russia, staying ahead of him the entire way.
As they reach the Arctic Circle and travel over the pack ice of the Arctic Ocean, Frankenstein, suffering from severe exhaustion and hypothermia, comes within a mile of the creature, but is separated from him when the ice he is traveling over splits. A ship exploring the region encounters the dying Frankenstein, who relates his story to the ship's captain, Robert Walton. Later, the monster boards the ship, but upon finding Frankenstein dead, is overcome by grief and pledges to incinerate himself at "the Northernmost extremity of the globe". He then departs, never to be seen again.

Frankenstein remains blind to the fact that he has let loose a power in the world, that he himself has assumed to be fearful, and even though the creature may not be aesthetically agreeable, he must remain accountable to his creation. Nevertheless, Frankenstein shrinks away from all responsibility and emphasizes that he is irreproachable of all transgression expect for the act of creation itself. Frankenstein, in effect, turns out to be an idealist and naïve young man who nonetheless has faced great and unparallel adversity. Despite the monster’s fervent appeals Frankenstein’s concerns assumingly remain with the well being his own species. In contrast to Frankenstein’s ostensible immobility, his helpless creation, frequently called the monster, is active. His love for his creator is unreciprocated and despite all his pleadings, he succeeds in making little favorable impression on Victor Frankenstein:

I am thy creature, and I will be even mild and docile to my natural lord and king, if thou wilt also perform thy part, the which thou owest me. Oh Frankenstein be not equitable to every other, and trample upon me alone, to whom thy justice, and even thy clemency and affection is most due. Remember that I am thy creature; I ought to be thy Adam; but rather the fallen angel, whom thou from joy for no misdeed. Everywhere I see bliss, from which I alone am irrevocably excluded .I was benevolent and good; misery made me a fiend. Make me happy, and I shall again be virtuous.
