What term describes the moral strength to do what is right even in the face of adversity?

The term that best describes the moral strength to do what is right even in the face of adversity is courage. Courage is not simply the absence of fear; it is the ability to confront fear, pain, danger, or challenges, and to act according to one's convictions. In military and ethical contexts, demonstrating courage means standing firm on principles and making decisions that align with moral and ethical guidelines, even when it may be unpopular or difficult.

Integrity, while closely related, refers more to the consistency of actions, values, methods, measures, and principles, as well as being honest and having strong moral principles. Honor pertains to the adherence to ethical conduct and respect that one earns through choices and actions. Respect involves recognizing the worth of others and treating them with dignity. These concepts are foundational and intertwined, but courage specifically highlights the action of doing what's right despite facing tough circumstances or opposition.
