Whether someone is a "good girl" is subjective and depends entirely on your definition of "good."

• Values: What values are important to you? Do her actions align with those values?
• Behavior: Is she kind, respectful, and honest?
• Context: Consider the context of her actions. What might seem "bad" in one situation could be understandable in another.

Ultimately, "goodness" is a matter of perspective and personal judgment.
