The creature came to realization that the reason why the DeLacey family reacted that way after seeing him was because he is scary looking. The creature no longer has hope in humanity. Now, he decides that he is going to find Victor, his creator.
In order to get to Victor, the creature must make his way to Geneva. On his way, he sees a little boy in the woods outside of Geneva. The little boy notices the creature. Then, the creature approaches the boy with no intention of hurting him. The boy reveals that he is William Frankenstein, a relative to Victor Frankenstein. This causes the creature to become furious, and hence kills William.
After the creature commits this crime, he roams through the mountains and happens to see Victor. He asks Victor to follow him to the cave so he can proceed to tell his story. He admits that he is lonely and miserable and thus requests for a female companion. He makes a promise; to take her to South America and never return.
Victor is now persuaded into creating the female creature. The creature lets Victor know that he will be monitoring his progress during the creation. For two years, Victor travels to England and Scotland and begins creating the companion.
When working on the companion, Victor catches the creature looking at him through the window. He then destroys the companion because he starts having second thoughts and believes that the female creature will act the way the male creature did.
The creature kills Victor's loved one, Elizabeth Lavenza, because he is frustrated his companion has been destroyed. Victor searches for the creature so he can destroy him and he is following the clues and hints that were left by the creature. He never catches him, although, he ends up on Walton's ship and tells him his story. After getting ill on the ship, Victor dies. Eventually, the creature sees and becomes very sad; he does not feel the satisfaction he believed he would feel.
