These concepts, however, are useful in decision making. Ethics is abranch of philosophy that stipulates what is right or wrong for individuals and the society at large while morality underpins the principles governing right and wrong(Vardy 18).Ethical theory has four broad categories; deontology, utilitarianism, rights, and virtues. Consequentialist theories such as utilitarianism opine that an action is good if the consequences are good, while deontological ethics argue that the goodness of an action is not determined by the consequences, but rather what is required.Kantian ethical theories are based on the following premises: duty, categorical imperative and reasoning.Immanuel Kant’s ethical theories are classified under the duty based portion of ethics.Deontological ethics is the branch of ethics that presupposes that doing something good should be out of duty, and not other reasons such as fear.He thought that goodwill was the test that everyone could use to justify what was good. This is because what is good is relative subject to personal or situational interpretations. He, therefore, posits that whatever is good must be regarded as good in all contexts(Aune 13).
