The novel “Frankenstein” written by Mary Shelly reflects the elements of the Gothic novel and Romantic novel. It tells about Victor Frankenstein's journey as a young scientist who develops a creature. This creature turns into a monster who at the end of the story runs behind Victor to kill him. When Victor dies, the monster laments over it and thus comes to this conclusion that he too will end himself so that no one ever could know about his existence. He says that though he wanted to kill Victor still his death has not given him peace. At the end, he jumped in the sea and finished himself. The way he lamented over his creator’s death and his decision to make himself invisible from the eyes of everyone reflects his humanity which he gained in the end.
