Which statement reflects a fundamental principle of individualism in ethical decision-making?

The statement that long-term self-interest should guide ethical actions aligns with the principle of individualism in ethical decision-making. Individualism emphasizes the importance of personal autonomy and the value of each person's self-interests in determining ethical behavior. This perspective suggests that individuals should prioritize their own well-being and fulfillment while making decisions, as long as these actions do not infringe on the rights of others.

By focusing on long-term self-interest, individuals can cultivate an ethical framework that promotes their own goals and values, leading to a more fulfilling life. This approach encourages self-reflection and accountability, as individuals are responsible for their choices and the consequences that arise from them. In contrast, the other options reflect different ethical perspectives that prioritize community norms, adherence to rules, or collective interests over individual considerations, which are not aligned with the principle of individualism.
