Meaning of "she didn't know what to think"

Question

some weeks later, the door of Esmeralda’s cell cracked open. A shaft of blinding light entered from the world outside. Then the door closed again. A human form, holding a lantern, stood before her. “Who are you?” she asked. “A priest,” was the simple answer. The sound of that familiar voice made her tremble. She knew immediately that her visitor was Claude Frollo. “Are you ready?” he asked. “For what?” “To die. Your execution will be tomorrow.” Esmeralda clenched her pale, thin fingers. “Why have you done this?” she asked sadly. “What have I ever done to harm you? Why should you hate me so?” “But I love you!” Frollo exclaimed. Her tears suddenly stopped. In spite of her fear, she stared at him in confusion. A drop of cold water fell upon her cheek. She didn’t know what to think.

Dose it mean: she didn't know what is wronge or right?

Or dose it mean:she didn't know what to do?

Answer 1

It expresses a state of confusion, uncertainty or mixed emotion so intense as to impede thought. It might, in any given case, be confusion over right and wrong, but I would say that it is not usually so.

In this case, a man is declaring his love for her while ordering or cooperating in her death. She is getting conflicting information, and doesn't know what to make of it - at least initially.

If a person doesn't know what to think, they will usually not know what to do - thought it might also occur in cases where there is no question of doing anything. But a person can know what to think, or it might be put as what they think, while still not knowing what to do. It is even true that there will be cases where a person knows what they must do, but doesn't know what to think. I would say it is usually about dealing with conflicting information, emotions or evidence.
