Which term refers to behavior that is grounded in strong principles about right and wrong?

The term that best describes behavior grounded in strong principles about right and wrong is "ethical behavior." Ethical behavior refers to actions and decisions that conform to accepted standards of conduct, reflecting consideration of what is right and wrong. It encompasses not only legal obligations but also moral obligations, often involving a thoughtful reflection on principles, values, and what is considered just.

In this context, "good moral character" relates to an individual's overall integrity and ethical standards, particularly in the eyes of immigration authorities. However, it is somewhat broader and often assessed concerning conduct over time rather than a specific focus on principles. "Legal conduct" strictly refers to actions that adhere to the law without necessarily considering moral implications, while "moral integrity" speaks to upholding moral principles consistently.

The choice of "ethical behavior" captures the essence of acting according to a strong moral compass, emphasizing the importance of principles in guiding actions.
