Madness and the dark side of human nature certainly seem
to be two of the major themes of Poe's classic short story. I've included some examples
below.

• The murderer tries to explain to the
  reader that his careful plans are not a sign of madness, but his actions suggest
  otherwise.


• The narrator claims to hear things that emit
  from unearthly sources.


• The narrator claims that he has
  no specific reason to kill the old man other than his "vulture
  eye."


• His careful preparation to kill the man in his
  sleep shows a dark side of the man's character.


• The
  dismemberment of the body is a particularly gruesome task that could only have been
  carried out by a man filled with either mental instability or pure
  evil.


• His belief that he can still hear the heart beating
  is further proof of madness.
