[Toy Soldier]

No. He's far too blunt and while he does occasionally try to be manipulative, he's not very good at it. He's a terrible liar.

He suffers from an anxiety disorder quite clearly, and it's manifesting as selfishness and paranoia. While sociopaths can and do experience anxiety (sometimes high levels of it), classically a sociopath would NOT show that in public, and Lewis is very upfront with his. He also has a very high regard for "truth" (as he sees it) and the ins and outs of every situation being known, even if the truth is detrimental to his own social position which is basically the opposite of sociopathy - sociopaths lie constantly for their own social benefit (e.g. Trump on twitter...)
