If you answered yes, you were probably using a form of moral reasoning called "utilitarianism." Stripped down to its essentials, utilitarianism is a moral principle that holds that the morally right course of action in any situation is the one that produces the greatest balance of benefits over harms for everyone affected. So long as a course of action produces maximum benefits for everyone, utilitarianism does not care whether the benefits are produced by lies, manipulation, or coercion.
