O wretched state, o bosom black as death!
– William Shakespeare
Hamlet, Act 3, Scene 3. Claudius shows guilt at the murder of the King Hamlet. His "wretched state" implies melancholy, an emotion that he doesn’t normally express, suggesting that he may be feeling suicidal. His "bosom black as death" comment shows he acknowledges the corruption inside of him and damage he has brought to Denmark.
