Situation ethics is a relativist moral theory developed by Joseph Fletcher in 1963 based on the idea that the morality of an action depends on the situation rather than any fixed rules. It is inspired by Jesus' message of love (agape) as described in the Bible. Fletcher argued morality should be flexible rather than legalistic or anti-nomian. Situation ethics considers the outcomes and consequences of actions, placing primary importance on love as the sole intrinsic good. While it aims to avoid conflicts between duties, critics argue it could allow any action and that determining the most loving choice is subjective.
