What causes corruption? What prevents it?

Students read the play "The Picture of Dorian Gray," the tale of a man who sells his soul to a mysterious painting in order to retain his youth. With every corrupt action Dorian takes, however, the painting publicizes his evil.

Today we watched the film, and students took notes about the light and music direction. They also wrote key words that may be factors leading to corruption.

Pride
Distrust
Terror

Finally, some notable quotations from the play include:
"But when your youth goes, your beauty will go with it, and then you will discover that world doesn't want you anymore." (Lord Henry)
"Evil is a thing that writes itself across a man's face." (Basil)
"I will kill the past. When that is dead, I will be free." (Dorian Gray)
