Which of the following is NOT a characteristic of an ethical action?

An ethical action is generally characterized by an awareness of and concern for the impact of one's actions on others. The option identifying that an ethical action is best for oneself without regard for how it affects others lacks this essential characteristic. Ethical behavior takes into account the well-being and rights of all individuals involved, striving for actions that are fair and just for everyone.

In contrast, actions that are beneficial to everyone involved, are universally accepted, and align with established moral guidelines reflect a strong ethical foundation. These characteristics highlight the importance of considering the broader implications of one's actions rather than prioritizing personal benefit at the expense of others. Thus, option C stands out as it fundamentally contradicts the core principles of ethical decision-making.
