Frankenstein (8) - Nature vs. Nurture

"I am malicious because I am miserable." (pg. 104)

A major theme of the novel is nature vs. nurture. In the beginning, the reader is led to believe that the creature was evil from creation because of Victor's reaction. However, the creature argues that he was good in nature. He became evil because of the way he was treated. The creature believes his actions were caused by his loneliness and misery. The creature was kind and took care of the DeLaceys even though they did not know it. He did not turn against humans until people attacked him. First, the DeLaceys ran him off and then he was shot when he saved a little girl. He claimed this was the reason for his evil actions. So the question is whether it was nature or nurture that made the creature evil?
