So I’m reading this novel called, Jane Eyre, but I would like to know a key topic, Jane faces a struggle between conscience and passion throughout the final section, Considering the last few chapters of the novel, does conscience or passion win and How does her fight between conscience and passion contribute to the novel as a whole?
