FWIW, here's my theory on CW in the marriage...
All levels of narcs (both those with serious personality issues who are dangerous and those run-of-the-mill annoying types) LOVE attention and will often hookup on a regular basis (long term relationship, or marriage) with someone whom they can a) control, b) not get too much grief from, c) take care of their needs (cooking/cleaning/childcare/sex) and most importantly, d) feed their egos. These people they hook up with are often meek/dependent in relationships due to their own lack of self-worth, or illness or other life issues that leave them feeling "less than"...sometimes it's just naivety and the need to be a "good person" no matter what.
These hookups seriously stroke the narcs egos, as in SM posts that tell the world how great their narc spouse is, and, by being cute, fit and alluring (arm candy).
Often the narc carries on affairs, physical and emotional, with others, especially when the ego stroking at home tones down due to the passage of time, responsibilities (work, kids, etc.) and/or the spouse starts to see through them and begins to set his/her boundaries, or retreats to lick his/her emotional wounds.
I believe that some of these narcs begin to realize they're "tiring" of the current situation and start looking for a way out, not always an evil way out, but a way out. That's known as the "discard" phase. This is when they will begin to further cultivate whatever affairs they are having, and/or look for new sources who can supply them their needs (mostly ego needs).
Most of them have harems of sorts; other people they can flirt with and manipulate...and often they will use these harems (sometimes known as "flying monkeys" - think Wizard of Oz and the monkeys that kowtowed to the Wicked Witch) against their current spouse - this is referred to as "triangulation". It's a means of hurting the spouse to keep him/her line and under control and a way to "notify" him/her that she'd better kowtow and not make waves...plus it fulfills a narcs nasty need to hurt others in order to lift him/herself up in their own eyes. Kind of an emotional "dupers delight".
I believe CW had probably been having affairs while in on-going relationships most of his adult life. I would bet that someone close to him (most likely family, as narcs don't have many close friends) knows some of his history and personality issues. I believe he reached the discard phase, in a big way, and is one of those narcs who is a psychopath.
It would be very enlightening to know how many jobs he's had, any firings (if so, reason for firing), any other lawbreaking behavior and at what age, and more of his family history. Would love to hear from past relationships also!
EDITED for clarification.
