That's pretty common for a narcissist actually. They're incredibly manipulative and attempt to control everyone and everything. The most successful are often high-powered CEO's and entrepreneurs - but even they often have chaotic, 'out of control' social lives - multiple divorces, poor relationships with peers, family, and their kids, etc. It's gotta be like a juggler keeping 20 balls up in the air - their whole being is based on lies, manipulation, control and a fragile facade - and eventually a ball, or ten, are going to fall. No one can tell a narcissist where they're going wrong because narcissists are never wrong. Never. And...if someone does call them out for their bad behaviour, a narcissist will adapt their behaviour to be more covert (like less physical, but more emotional or financial abuse) or the narcissist will simply cut ties - totally - with their detractors.
Personally, if I'm right with my armchair dx, I don't see OP learning any lessons from this experience. Not killing Reeva, not facing trial, not prison, and not post-prison restrictions. OP, if he is a narcissist, will always feel he is 'above' any punishment and is being maliciously persecuted. I'm not an optimist when it comes to NPD - they're highly resistant to treatment as nothing is wrong with them - it's the rest of the world at fault. And in this case no treatment will even be available since apparently nothing is amiss. Um. Yeah. Okay.
In prison, I think he will adapt very well - that's what narcissists do out of necessity for survival - they adapt constantly and become highly skilled at it.
