Not too easy. Not too difficult.
Business ethics is learning well-thought out ethical theories and principles, from Aristotle, to Kant and Mills, and trying to use any theory to justify an action taken by a business. Yes, there was some discussion on how corrupt companies can be (Enron for example) but it was basically a course on how to justify a company's actions even when it negatively affects people.
The course allowed for engaging conversation and for students to speak their opinion. It also gave insight on how corporations function in terms of their ethical boundaries.

Advice for students:
Before you take business ethics I would advise taking a philosophy class on ethics. Have a good understanding of Aristotle's Means Between Extremes, Kant's Categorical Imperative, and Mills' Utilitarianism.
