Reason for the Characterization of Jane Eyre

We know about the two categories that women were placed in (monster and angel) and in class we talked about why Jane was characterized the way she was (a mixture between the two stereotypes). Charlotte Bronte clearly had the idea of monsters and angels in mind when she characterized Jane as a balance between the two as she was trying to prove that women are not just angels and they should not have to be. If Bronte wanted to prove the point that women are not complete angels then why did she decide to show Jane as a balance between the two instead a complete monster? We mentioned that it could be because Bronte would be ridiculed if she made a novel with the main character being very open about her monster-like qualities, but I think it is because Bronte wanted to show that women can not be placed in one category or the other. It is wrong to think that "the whole education of women ought to be relative to men. To please them, to be useful to them, to make themselves loved and honored by them, to educate them when young, to care for them when grown, to counsel them, to console them, and to make life sweet and agreeable to them-these are the duties of women at all times, and what should be taught them from their infancy" (Jean Jacques Rousseau). Women today and in the past have become extremely successful without the help of men and they should not aim to make men happy, but rather themselves. Charlotte Bronte wanted to help to raise awareness about issues/ideas that are still relevant today. For example, now we have characters like Katniss Everdeen who is obviously very independent, intellectual, and strong but is also "angelic" in her self-sacrifices, just like how Jane had qualities from both the monster and angel side. I believe that Bronte made Jane the perfect balance between angel and monster to not only avoid being made fun of for making such a "foolish" character but also raise awareness and prove that women should not be categorized.
