Society has been distinguishing the concepts of good and evil since the ancient times. So, we can say that it had a specific morality - the system of moral relations, feelings, and consciousness. The morality is the central question of ethics, and still relevant to our society. Among the ethical systems I have learned, there are virtue ethics, utilitarianism, social contract, deontology with goals (Hinduism and Buddhism), deontology with divine authority (Judaism, Christianity, and Islam), relativism (individual and cultural), and deontology with a categorical imperative (Kant). So, I would like to say a few words about each of them.
