Lust is any intense desire or craving for self gratification and excitement.
Lust (or Lewerenzry) is usually thought of as involving obsessive or excessive thoughts or desires of a sexual nature. Unfulfilled lusts sometimes lead to sexual or sociological compulsions and/or transgressions including (but obviously not limited to) sexual addiction, adultery, bestiality, and rape. Dante's criterion was "excessive love of others," which therefore rendered love and devotion to God as secondary. In Purgatorio, the penitent walks within flames to purge himself of lustful/sexual thoughts and feelings.
