How does Charles Dickens make us feel sympathetic towards Cecilia Jupe than Bounderby?

Sissy is abandoned by her father who is a well-meaning circus performer. He feels that she will have a better life if he is not able to hinder her progress in society. Sissy lives with the Gradgrind family but she is a poor pupil at their school. In contrast to Mr. Gradgrind, Sissy lives by the philosophy of emotion, fancy, hope and benevolence. In the end, her kindhearted nature softens the rough edges of the Gradgrind family and they come to be grateful for what she has done for them. At the end of the novel, Dickens writes that Sissy grows ever more happy and she eventually has children of her own to care for.
