The way how he tries to mimic human expressions when he's laughing with the laugh track on his tv or his fabricated story about the bike which would be believable to anyone who hasn't seen the scene before it, or the fact he'll get anyone killed just to get that shot of the year.
He'll manipulate anyone, do anything it takes to score the perfect shot, how he manipulates Nina for sex shows his lack of boundaries, seeing anyone besides himself as objects. And the ending with him telling his new crew that he wouldn't get them to do anything he wouldn't do himself and we all know that his twisted mind has no bounds, and this entire time he's still human he could be your neighbour, your kid, even yourself.
