Lust is one of the Seven Deadly Sins from Abrahamic Lore. It is an intense desire for something such as sex but also an intense desire for physical or non physical desire or luxury. One can lust for power and knowledge just as one can lust for drugs and food. In Buddhism, one of the Ten Precepts used to train novice monks tells them to refrain from lust. In Hinduism, Krishna proclaims lust to be one of the sins that is a gateway to hell. The demon of lust is Asmodeus and the corresponding virtue is Chastity.
All demons who offer love are considered demons of lust.
