Answer:
B. "I was benevolent and good; misery made me a fiend. Make me happy, and I shall again be virtuous.
Explanation:
Mary Shelley's "Frankenstein" tells the story of a monster whose creator rejected him. The young scientist who created him, Victor Frankenstein, brought upon himself a series of misfortunes with this rejection of his own created being.
The theme of good and evil in an individual can be seen in the monster when he said "I was benevolent and good; misery made me a fiend. Make me happy, and I shall again be virtuous." (Chapter 10). In this chapter, the monster had confronted his creator Victor, as he had been following him. Stating his case, he admits that his personality is a result of the treatment he gets from everyone. He can change and be virtuous if he is made happy. This theme revolves round the dual personality of a person, capable of being good or bad depending on the situation and conditions.
