Deontological ethics is an ethical theory that emphasizes the importance of duty and adherence to rules or obligations in moral decision-making. Unlike consequentialist theories that focus on the outcomes of actions, deontological ethics asserts that certain actions are inherently right or wrong regardless of their consequences. This tag encompasses discussions around key figures in deontological thought, such as Immanuel Kant, and their contributions to moral philosophy. Additionally, it highlights applications of deontological principles in various fields, including law, medicine, and business ethics.
