In Chapter 12 of Mary Shelley's "Frankenstein," the narrative shifts to the perspective of the creature, who tells his story to Victor Frankenstein. The creature begins by describing how he came to consciousness after being created by Victor. He remembers feeling confused and alone, and he struggled to understand his surroundings and the sounds and words that he heard.
The creature quickly realizes that he is different from all other beings, and he is shunned and rejected wherever he goes. He is unable to find shelter or companionship, and he is forced to live a life of loneliness and isolation. Despite this, the creature is intelligent and curious, and he spends much of his time learning about the world and studying the habits of humans.
The creature's only hope of finding acceptance is to reveal himself to a human and hope that they will understand and accept him. However, whenever he tries to approach a human, they are terrified by his appearance and they run away in fear. The creature becomes increasingly angry and resentful towards humanity, and he begins to harbor a deep hatred towards his creator, Victor Frankenstein.
As the creature's story continues, he tells Victor about how he came to learn about the history of the world and the stories of the past. He also tells Victor about how he came to understand the concept of good and evil, and how he struggled to decide which path to follow. Despite his desire to do good, the creature is constantly rejected and mistreated by humans, and he becomes increasingly bitter and vengeful.
In the end, the creature pleads with Victor to create a companion for him, someone who will understand and accept him. The creature promises that if Victor creates a mate for him, he and his mate will leave humanity alone and live in peace in a distant land. Victor is torn by the creature's request, but ultimately he decides that it is his responsibility to prevent the creation of another being like the creature.
In conclusion, Chapter 12 of "Frankenstein" presents the story of the creature, who is rejected and mistreated by humanity due to his appearance. The creature's loneliness and isolation drive him to seek companionship and acceptance, but his efforts are in vain. The chapter also explores the theme of the consequences of playing God, as Victor is faced with the difficult decision of whether or not to create another being like the creature.
