I agree, I'm not sure that an ethics course will make people behave ethically. As part of my former life, I had to take an Ethics course for my accounting license. It focused on topics like conflicts of interest. Even though many professional (licensed) accountants have taken the ethics course and passed an ethics exam, it doesn't mean that much. Ultimately, behaving ethically will come down the individual's morals.
