What is the relation between ethics and metaphysics?

Ethics is concerned with determining what is morally right or wrong, while metaphysics deals with understanding the nature of reality and existence. The relationship between the two lies in the ethical implications of metaphysical beliefs, as one's beliefs about the nature of reality can influence their ethical judgments and actions. For example, if someone believes in a metaphysical principle such as moral realism, they may argue that certain actions are objectively right or wrong based on that belief.
