I'm not entirely sure what you're driving at. It seems you're equating having a routine with being a psychopath. While narcissism like in your extract can be considered part of the dark triad, it seems like you've decided the OP is also a narcissist with little to no evidence to back it up. Then again, I can only guess at what you're getting at when your only statement (argument?) is a quote from a piece of fiction.

Working out regularly does not make you a narcissist. In fact, he doesn't even specify the exercises he does. For all we know, he goes jogging to help boost his cardiovascular health, rather than pumping iron. And even if he did pump iron, let him. It's what he wants to do, and it doesn't make him a psycho.
