"I do not listen when anyone uses the word immoral,' said the Wizard. "In the young it is ridiculous, in the old it is sententious and reactionary and an early warning sign of apoplexy. In the middle-aged, who love and fear the idea of moral life the most, it is hypocritical."
"If not immoral, then what word can I use to imply wrong?" said Elphaba.
"Try mysterious and then relax a little. The thing is, my green girlie, it is not for a girl, or a student, or a citizen to assess what is wrong. This is the job of leaders, and why we exist."
"But then nothing would keep me from assassinating you, did I not know what wrong was."
