Additionally, if an action by a person was an act that was “not good,” but the consequences turned out to be “good,” under some theories of teleological reasoning, the act may be deemed a good ethical act. In teleological reasoning, a person will do the right thing if the consequences of his or her actions are good. Teleological reasoning takes into consideration that the ethical decision is dependent upon the consequences (“ends”) of the actions.
Utilitarian ethics is a normative ethical system that is primarily concerned with the consequences of ethical decisions therefore it can be described as a teleological theory or consequentialist theory, which are essentially the same thing, both having a notion that the consequence of the act is the most important determinant of the act being moral or not.
