Utilitarian

In ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for the affected individuals.[1][2] In other words, utilitarian ideas encourage actions that ensure the greatest good for the greatest number... Utilitarianism is a version of consequentialism, which states that the consequences of any action are the only standard of right and wrong... Though the seeds of the theory can be found in the hedonists Aristippus and Epicurus, who viewed happiness as the only good, and in the work of the medieval Indian philosopher Śāntideva, the tradition of modern utilitarianism began with Jeremy Bentham, and continued with such philosophers as John Stuart Mill, Henry Sidgwick, R. M. Hare, and Peter Singer. https://en.wikipedia.org/wiki/Utilitarianism
