The answer is "Utilitarianism".
Utilitarianism is the possibility that the ethical worth of an activity is exclusively controlled by its commitment to general utility in expanding bliss or joy as summed among all individuals. It is, at that point, the aggregate utility of people which is critical here, the best satisfaction for the best number of individuals. Utility, after which the tenet is named, is a measure in financial aspects of the relative fulfillment from, or attractive quality of, the utilization of products. Utilitarianism would thus be able to be depicted as a quantitative and reductionistic way to deal with Ethics.
