The ethical decision maker in this case is Tina, because she is the one who is facing the ethical dilemma. The ethical dilemma that Tina faces is whether or not she should keep her job and do what her boss tells her (which is unethical and potentially not legal) or if she should stay true to herself, and keep her integrity but risk losing her job.

For Tina's boss her interest is for Tina to go through with what was asked of her, but if Tina doesn't, the boss can simply hire a new intern. The customer's interest is using a trusted, reliable source of information online and this value is at stake if Tina goes online and makes pseudonyms with fake names and such.

From a deontological perspective, what the boss is asking Tina to do is always wrong because it is unethical and not legal so Tina should quit her job. From a virtue ethics perspective Tina should…
