But how did I murder her? Is that how men do murders? Do men go to commit a murder as I went then? I will tell you some day how I went! Did I murder the old woman? I murdered myself, not her! I crushed myself once for all, for ever.… But it was the devil that killed that old woman, not I. Enough, enough, Sonia, enough! Let me be!

- Fyodor Dostoyevsky
