Final answer:
The primary benefit of clear rules about behavior is the development of wider ethical rule systems, which create a consistent framework for behavior that aids in social cohabitation and trust. While some posit judging other cultures or intervening to protect human rights as a benefit, this is contingent upon a society's foreign policy goals and the acceptance of universal moral standards which is debated, particularly in the context of Normative Ethical Relativism.
Step-by-step explanation:
The benefits of clear rules about behavior include the development of wider ethical rule systems and potentially judging other nations/cultures and intervening to save innocent life. However, the latter is more contentious and depends largely on the overarching principles that guide a society or country in their foreign policy decisions. Developing broader ethical frameworks allows societies to establish consistent expectations for behavior, contributing to social order and allowing for the development of trust and predictability within communities. These frameworks can sometimes lead to the judgment of other cultures or the intervention to protect human rights, but this is not a given benefit, rather a possible extension of having clear rules about behavior.
Normative Ethical Relativism challenges the idea of universal moral standards, suggesting that moral judgments should be based on cultural context. This complicates the argument for intervening in other societies to save innocent lives, as it raises questions about the imposition of one culture's morals over another's. Nonetheless, clear behavior rules are essential to cohabitation because they facilitate interactions by setting expectations and reducing conflict, akin to traffic regulations enabling safe transportation.
