Human life by the progress of the times has changed so much. As a result, our society is becoming more diverse and specialized unlike in the past, and in the process, there have been large and small conflicts. This situation has constantly demanded that human beings, who are social and relational beings, solve the problem of conflict, and the resolution was largely done by law, not by morality. However, despite the moral approach that we have learned through education, the law controls our lives more than morality, which solves the problems of conflict. Also, as the logic of the law rules our lives, human relations have transformed into a contractual rather than moral aspect, and the only solution to conflict over these relationships is the law. This article examines whether the problem of conflict in human life cannot be resolved from a moral point of view. In other words, not only does it form more human relationships on the balance of law and morality, but it also tries to solve the problems of conflict morally. Therefore, based on Kant's position, this article seeks to minimize the error of legal moralism and legal positivism on the distinction between the two, not the dichotomy of law and morality. This will soon reveal more clearly that law as the efficiency of domination and morality as the justification of domination are complementary to each other.
