And in the middle of the book, after all Pip had done to him after he became a gentleman, Joe was still loving and affectionate towards him when he became ill. Also, throughout the book, Joe was proud to be who he was. He never wanted any property or money. Even when Mr. Jaggers offered him money because he would not have Pip as his apprentice anymore, he did not accept it. In contrast, Estella is a very dynamic character; she goes from being a girl with a heart of ice to a sensitive woman, although the change in her takes place late in the book.
At the start of the book Estella is very mean and insulting to Pip. This is not her own nature, and that is why it is possible for her to change into a better person. Estella was brought up by Miss Havisham to crush the hearts of all men, so that is what she does to Pip. Since Miss Havisham is the only family Estella has ever known, she is bound to her.
Since she is bound to Miss Havisham, she is obligated to serve as her tool of vengeance. But, when Miss Havisham dies, that bond is gone and more of Estellas true nature can come out. Since Estella is, at heart, a well-meaning person, she does soften up. This occurs after she has experienced hard times as Bentley Drummles wife, wich forces her to convert, and her cruel personality is finally destroyed by her true nature. At the end of the book Pip realizes that she has changed and thinks: .
. . what I had never seen before, was the saddened softened light of the once proud eyes; what I had never felt before, was the friendly touch of the once insensible hand. (Chapter 59).
