If you want to take the 4channish reading really literally, I think there's something interesting in the way the sigma-male hitman reaches a sort of detente with a tech-exec master of the universe--essentially an agreement not to bother each other too much. But I think taking that too far probably makes my reading a bit too 1:1 allegorical. I mean, quite literally, from a plot perspective, as someone else points out in these comments, he doesn't kill the guy because his face is caught on camera in the elevator--another example of the character's frequent slips.
