* Evidence: She shows some sympathy for Bertha, occasionally defending her against Rochester's accusations. She also seems to be aware of the truth about Bertha, even when denying it.
* Conclusion: Grace Poole may be a conflicted figure, caught between her own desires for stability and her conscience. She may be aware of the injustice inflicted on Bertha but feels powerless to change it.
4. Grace Poole is a symbol of the societal constraints on women:
* Evidence: Her limited role in the story and her lack of agency highlight the societal limitations placed upon women, particularly women of her social class. She is a symbol of confinement and oppression.
* Conclusion: Grace Poole represents the plight of marginalized women in Victorian society, forced into roles that often conflict with their own desires and agency.
Ultimately, Charlotte Brontë leaves the true nature of Grace Poole open to interpretation. This ambiguity reflects the complexity of human nature and the difficulty of judging others based on limited information. The reader is left to draw their own conclusions, adding to the depth and richness of the character.
