Crime and Punishment question

Hi, friends. I recently read Distoevsky's Crime and Punishment. Although it made a strong impression on me, I did not understand how it can make a compelling case to be moral. I understand I am holding a minority view. Raskolnikov, even at the end did not think that the murder was a crime. He was even convinced that he is not like Napoleon and could not "step over". Let alone building a case for morality for Napoleon-like people, it doesn't even build a case for the next-best kinds like Raskolnikov. Please let me know what you think.
