Groups of people behave differently than individuals. Corporations are constructed with the entire purpose of something that an individual wouldn't or couldn't do. It is the job of a board member to ensure that. A person in a company making a moral decision involving the company's behavior isn't acting from a sense of personal morality because it isn't happening to them. The consequences aren't generally on them, other than losing their job. Yes, companies can be amoral, but not for the same reasons that people can be amoral.
