The weird thing is, the beginning of the article says he's NOT psychotic.
I just finished reading "Under the Banner of Heaven", about the throat-slitting murder of their sister-in-law and her baby by Ron and Dan Lafferty, fundamentalist Mormons and self-appointed "prophets", because she wouldn't stay silent about the Lafferty brother's horrible mistreatment of their wives and children.
It also tells the story of the vicious violence of the mainstream Mormons in brutally slaughtering a group of about 130 innocent "gentile" men, women, and children, called the Mountain Meadows Massacre, which was caused by the hate-filled vengence speaches given by the Mormon "prophet" Brigham Young, as well as by his direct order.
Ron Lafffety was found sane enough to stand trial and sentenced to death. The doctors said he was not psychotic, but he did exhibit the symptoms of a psychological affliction called narcissistic personality disorder (NPD). He, like other "Prophets" and "Gurus" had an exaggerated sense of self-importance, a preoccupation with fantasies of unlimited success, power, brilliance, beauty, or ideal love.
These people believe that they are special. They require excessive admiration, have a sense of entitlement, selfishly takes advantage of others to achieve their ends, lack empathy, and are often envious of others or believe others are envious of them.
They shows arrogant, haughty, patronizing or contemptuous behavior or attitudes. They have an exaggerated desire to mete out justice, often erupting with self-righteous indignation against those breaking rules, but have no compuntion about breaking rules themselves. The rules "don't apply to them".
