How can someone lead such a double life?

Here's a link to a story I worked on last week, now published in the Western Catholic Reporter:

WCR This Week   Narcissism leads abusers to double life January 23, 2012 DEBORAH GYAPONG CANADIAN CATHOLIC NEWS Bishop Raymond Lahey's double life while serving as a bishop in the Catholic Church might partly be explained by narcissism say experts who have worked with troubled or accused priests. In December, the forensic psychiatrist who examined the 71-year old bishop told Lahey's sentencing hearing, he was a homosexual who had been involved in a "number of one-night stands" before entering a 10-year relationship with a man that he hoped to continue when he got out of prison. -snip- "What causes a man to maintain this kind of double life for so long is basic narcissism, the idea that I'm entitled to this, I can do whatever I want; if I want to lead a double life I'll have a double life," said psychologist Peter Kleponis. -snip- Narcissism can grow as priests climb the ladder and become bishops, thinking of themselves as a prince of the Church who is above everything, he said. "Narcissism is very common in addicts, because even though they know what they are doing is bad, and know it is wrong, they decide, 'I'm going to do it anyway,'" Kleponis said from his office in West Conshohocken, Pa. Kleponis and his colleague Dr. Richard Fitzgibbons, a psychiatrist who is a consulter to the Congregation for Clergy in the Vatican, have worked in dioceses across the United States. "Severe narcissism is a major reason why a priest or other men choose to sexually abuse a minor," Fitzgibbons and co-author Dale O'Leary wrote in the article "Sexual Abuse of Minors by Catholic Clergy" in the August 2011 issue of the Linacre Quarterly, the journal of the Catholic Medical Association in the United States. "Not having one's needs met during childhood can create a situation in which a person believes they must meet their own needs."
