Throughout the narrative Bronte's writing exhibits sympathy for displaced persons. First of all, the plight of the orphan is certainly one that Bronte and other social reformers held as a cause celebre. Jane, Helen, Adele all exemplify the need that these orphans have for love and security.
Early in Jane's life she did not have a tremendous compassion for displaced individuals. Her aunt and cousins are tragic characters when she meets them, but she is not particularly considerate or understanding of them as such. When she gets to Lowood, Jane becomes a champion for her friend Helen, and from there we see a fairly consistent pattern of such behavior. She is Adele's champion when she thinks Mr. Rochester is not attentive enough to her, and she even feels some empathy for those in a class above her who are overlooked or scorned--including the family which abused her and sent her away. The change seems to happen once Jane finds her own moral compass. She was treated unfairly as a young girl and therefore came to value others as fairly as she is able. When they are not treated that way by others, she becomes their champion.
