Kantian Ethics is derived from the philosopher Immanuel Kant and is a form of Deontological ethics. Deontological ethics is a type of ethical theory that judges whether an action is morally permissible or impermissible by comparing the action to a series of rules and maxims, rather than judging the morality of an action based on consequences, which would fall under the branch of Teleological ethics such as utilitarianism in which an action ought to be done if it creates the best possible consequences.
