How does Bronte present Jane as pro-active in the novel as a whole?

Throughout Jane Eyre, Bronte shows Jane as a person who stands up actively for what she thinks is right.
For instance, early in the novel, Jane, as the poor relation, defends herself against Mrs. Reed, when Mrs. Reed falsely and cruelly tells Mr. Brocklehurst Jane is a liar. The young Jane, though badly oppressed, must set the record straight. Not only is she not a liar, she is a person who cannot keep silent about falsehoods. She could have taken the verbal abuse, but instead she goes after Mrs. Reed actively, even though it might have been in her best interests to say nothing:

SPEAK I must: I had been trodden on severely, and MUST turn: but how? What strength had I to dart retaliation at my antagonist? I gathered my energies and launched them in this blunt sentence
I am not deceitful: if I were, I should say I loved you; but I declare I do not love you: I dislike you the worst of anybody in the world except John Reed ...

Later as a governess and Mr. Rochester's beloved, Jane's strength of character again causes her to respond pro-actively when she realizes Mr. Rochester is trying to marry her while his first wife is still alive. For someone who has spent her life longing for love and acceptance, it is heart rending for her to have to give up the man she loves. However, she will not violate her morals and live with a married man. Jane leaves—risking death to venture out alone—rather than staying in a situation with Mr. Rochester that compromises her.
She shows agency and will as she refuses St. John's offer of marriage. She also responds pro-actively to the "mysterious summons" of Mr. Rochester. His voice sounds in her head, calling out her name. She first boldly orders St. John away:

It was MY time to assume ascendency. MY powers were in play and in force. I told him to forbear question or remark; I desired him to leave me: I must and would be alone. He obeyed at once. Where there is energy to command well enough, obedience never fails.

Jane takes matters in her own hands by returning to Mr. Rochester, even though it might have seemed irrational that he could speak to from so far away. Throughout the novel, despite her disadvantages of being small, plain, and poor, Jane is true is true to herself and actively does what she believes is right. This leads to a happy ending for her.
