Why write Frankenstein?

Mary Shelley wrote Frankenstein many believe in retaliation to the excesses of the industrial revolution. Many in Shelley's time believed that mass production was the primary cause of the social issues of the time. These issues included poverty, urban over crowding, and dangerous working conditions in hazardous factories. Mary saw England's industrial transformation as a serious threat to individual ideals, and this is evident in her emphasis on unchecked progress in the field of science in Frankenstein.
Frankenstein a man driven by his own obsessions.

Narrative Style of Frankenstein
The narrative framework of the novel has three different levels, encapsulating Walton, Victor and the creature. This writing style generates reader sympathy and empathy which alters with each version and discrepancies revealed within them. Mary Shelley presents the personality of each character clearly and distinctly. This is seen from the outset with the letters from Walton to his sister. Walton's letters establish a mood of evil forebodings that set the style and narrative journey that unfolds for the reader.
