Moral necessity refers to the idea that certain actions are required based on ethical principles or moral obligations. It suggests that individuals have a duty to act in ways that align with their values and the well-being of others. This concept often arises in discussions about ethics, where choices are evaluated not just by their outcomes but by the moral responsibilities involved. In many philosophical frameworks, such as those proposed by Immanuel Kant or John Stuart Mill, moral necessity plays a crucial role in determining what is right or wrong. It emphasizes that some actions are not merely optional but are essential for maintaining moral integrity and social harmony.
