Despite the happiness and the sense of acceptance that Thornfield and Rochester’s love offer, Jane knows that staying would be a type of self-imprisonment. Jane must choose between emotional exile and spiritual and intellectual imprisonment. She knows she must flee while she can.
Throughout the narrative of Jane’s trials, the reader not only gains insight into Jane’s personal constitution and character, but also into the society in which she lives. When Jane experiences the plight of the poor, the novel presents us with a bleak glimpse of a society in which the needy are shunned out of tightfistedness and distrust.
