B. "I was benevolent and good; misery made me a fiend. Make me happy, and I shall again be virtuous."
Explanation:
The theme, "Each person contains good and evil" means that we all have two sides embedded in us and it is shown based on challenges, situations, treatment and things we are being subjected to during the cause of our living. The good side manifests if the world around us isn't cruel or trains us to be good and compassionate while the other side also manifests if the world treats us with horror and hence becomes part of us.
