They say that the mythomaniac has to believe his lies in order to convince others of his enslaving deceptions; the father of lies, usually mimics a very similar behavior: many of the people he uses in his macabre plan to condemn them to eternal suffering, do not believe that there is an intellectual author of evil. Thus, there could not be a more favorable scenario to exercise dominion over the mind and give orders to kill, steal, destroy, and many other atrocities and sick behaviors.
2 Corinthians 4:4 NKJV
4 whose minds the god of this age has blinded, who do not believe, lest the light of the gospel of the glory of Christ, who is the image of God, should shine on them.
John 10:10 NKJV
10 The thief does not come except to steal, and to kill, and to destroy. I have come that they may have life, and that they may have it more abundantly.
