After pride, lust is the vice that the devil prefers to use to lure people away from God. Lust blinds the mind of a person, and since it is the mind that enlightens the will, once blinded, it no longer has the ability to lead the will away from the irrational urges of the body. Lust is an undiscerning passion that acts on fantasies, thoughts, and desires. Lust always leads to irrational, reckless, ruinous, and self-destructive behavior.
