Does David Lurue change, why or why not?

In the book Disgrace, David Lurie eventually changes. In the beginning chapters Lurie is arrogant and believes in not only white supremacy but also male dominance. His belief is demonstrated by his reverence for Western literature that he often refers to while teaching at the university. He belittles women as mere objects of beauty for pleasure fulfillment, as witnessed by his numerous affairs for the better part of his life. Even after he engages in an illicit relationship with his student Melanie, Lurie feels no remorse for his actions and opts to resign from his profession due to disgrace.
However, all this changes during his stay at the farm with his daughter Lucy, who is raped by three men, literally in his presence. The aftermath sparks feelings of guilt and shame for what he did to Melanie, and he heads back to Cape Town to apologize to Melanie’s father. He also seeks to work at the shelter and cremate dogs in order to ensure that their bodies are treated with dignity. He realizes that all creatures are equal and deserve to be treated with dignity and respect both when alive and dead.
