Now I hate to give the man credit, but when his house was burning down, Mr. Rochester did everything he could to keep everybody alive. It is the one redeemable thing he has. I had no idea Jane wanted to take that away from him.
The book tells the story of Rochester saving his servants and attempting to save Bertha: "Yes, indeed was he; and went up to the attics when all was burning above and below, and got the servants out of their beds and helped them down himself-and went back to get his mad wife out of her cell."
Jane argued that the scene should show Mr. Rochester flee the house leaving Bertha and the servants to fend for themselves. This seemed like an attempt to make her the clearer protagonist in the movie. She didn't want the audience to think that Mr. Rochester was a hero of any kind. I don't understand why these two are married.
