However, the "madwoman" is not actually crazy. She is Bertha Mason, Mr. Rochester's first wife, who he has cruelly imprisoned in the attic after deeming her insane.
Here's why Grace Poole is often associated with the "crazy woman" label:
* Her role: Grace Poole is presented as a somewhat strange and eccentric figure. She is responsible for keeping Bertha locked up and administering her medication.
* The narrative: Brontë crafts the narrative in a way that makes the reader initially believe Grace Poole is the one who is "mad." The descriptions of her behavior and the way she interacts with Jane contribute to this perception.
* The truth: As the story unfolds, it becomes clear that Grace Poole is merely a pawn in Mr. Rochester's scheme to conceal his past and keep Bertha hidden.
Ultimately, Bertha Mason is the true victim of societal norms and a controlling husband who uses the label of "insanity" to justify his actions.
