Immanuel Kent developed the modern “Deontological” ethical concept in the late 18 centuries. His theory concerned with duties and rights. “Rightness and wrongness”. According to deontological, “an action” is well thought-out morally good for some characteristic of the action itself and regarding their consequences, deontological ethics holds some acts of morality as obligatory for human well-being. By contrast, “Utilitarianism” (also called consequentialism) is a “moral theory” developed by Jeremy Bentham and John Stuart Mill. More focus on the effects of the personal action, Utilitarianism; believed “the purpose of morality is to make life essay by imprisoning the amounts of the good thing. Such as “pleasure and happens” by decreasing “the amount of bad thing in the world” (pain and unhappiness). Their central principle of ethics lies in conformity of an action to some regulation, and turn around on the idea of “the end justifies the means” although the deontological perspective on the concept “the end does not justify the means”.
