The person who grovels in depression and says he hates himself for having wasted his life would actually be glad that he had wasted his life if he really hated himself. In fact, he is unhappy about having wasted his life because he loves himself. The apparently remorseful criminal, who says he hates himself because of the crimes he has committed, should then be glad to see himself suffer in prison. Yet he hopes to escape that fate, which proves he loves himself in spite of his protestations of self-loathing.
