Hardy's "Jude The Obscure" has several themes, but the most evident is one that recurs in several of Hardy's writings. The morality issue is large. Jude does what he can do the best he can do it. He tries to remain a moral man and he makes the best decisions he knows how to make after looking closely at whatever situation he finds himself in. He tries to follow an ethical and moral path. They may not seem to be ethical and moral to the surrounding community but he is true to his values and when he sees that he has been wrong in his thinking or made a wrong choice, he accepts responsibility for his actions.
This novel is also about the freedom of choice for women. Sue is considered to be a "new woman" who acts on her impulses and does not try to live her life by Victorian standards.
