The document discusses two business ethics cases - the Merck & Co case and the slavery in the chocolate industry case. For the Merck & Co case, it analyzes Roy Vagelos' decision to develop a drug for River Blindness under Kohlberg's theory of moral development. For the chocolate industry case, it identifies systemic, corporate, and individual ethical issues including child labor, poverty wages for farmers, and lack of enforcement of anti-slavery laws. It concludes that African farmers, governments, chocolate companies, distributors, consumers, and those aware of the situation all share moral responsibility for the slavery.
