Develop a Fictional Dialogue in Which Two Characters Argue Over

Develop a fictional dialogue in which two characters argue over the nature of morality. The two characters should construct arguments and offer criticisms of each other's arguments. They can agree to disagree, or find some areas of agreement. The dialogue should address psychological and ethical egoism; duty-based, consequentialist, care-based, and virtue-based theories of morality; cultural and ethical relativism; and Nietzsche's attack on morality.
