It is usually thought of as intense or unbridled sexual desire, which may lead to fornication (including adultery), rape, bestiality, and other sinful and sexual acts; oftentimes, however, it could also mean other forms of unbridled desire, such as for money, or power. Henry Edward Manning explains that the impurity of lust transforms one into "a slave of the devil". Dante defined lust as the disordered love for individuals. It is generally thought to be the least serious capital sin, as it is an abuse of a faculty that humans share with animals and sins of the flesh are less grievous than spiritual sins.

Greed Greed (), also known as avarice, cupidity, or covetousness, is a sin of desire like lust and gluttony. However, greed (as seen by the Church) is applied to an artificial, rapacious desire as well as the pursuit of material possessions. Thomas Aquinas wrote: "Greed is a sin
