Government error that results in significantly higher funding for your organization.

Imagine this scenario: You work for a nonprofit organization that helps AIDS victims. You discover a government error that results in significantly higher funding for your organization. Do you keep the money or do you report the error? Which philosopher may help you supporting your choice? In your answer, explain what, presumably, the psychological and the ethical egoist would argue for. How would Aristotle reply? How would Sartre? Remember, the authors are offering arguments that are designed to convince their audiences of their positions.
