There is a luxury in self-reproach. When we blame ourselves we feel no one else has a right to blame us.

– Oscar Wilde

The Picture of Dorian Gray, Chapter 8. Dorian writes a passionate letter to Sibyl (she’s dead by suicide but he doesn’t know this), begging her forgiveness for his cruelty to her and accusing himself of madness. With twisted logic, he rationalizes that if he blames himself, then no one else can blame him.
