Here's why:
* Jane is mistreated by Mrs. Reed and her children: Mrs. Reed is unkind and favors her own children, John, Eliza, and Georgiana, over Jane. They bully Jane and she is often blamed for their misdeeds.
* Jane is sent to Lowood Institution: Mrs. Reed, driven by her own prejudice and resentment towards Jane, sends her to Lowood, a harsh and poorly run boarding school for girls. It's not a punishment for any specific act, but rather a way to get rid of Jane and make her life miserable.
The reason behind Mrs. Reed's behavior is complex:
* Social class and resentment: Mrs. Reed feels a sense of responsibility for Jane's well-being, but it's largely because of social obligation, not genuine care. She resents Jane for being a reminder of her deceased husband's brother and feels burdened by her presence.
* Jealousy and insecurity: Mrs. Reed may also be envious of Jane's strong spirit and independent nature, especially since Jane is a threat to her own children's place in the family.
It's important to note that Mrs. Reed's cruelty is ultimately driven by her own internal struggles and prejudices, not any specific wrongdoing on Jane's part.
