Sociopathic? Not necessarily. He's just being pragmatic. A sociopath is somebody who lie when he is expected to tell the truth. There's no real world for somebody who does the opposite (tells the truth even if he would be expected to lie), but most people are just pragmatic - they tell the truth to their friends and co-workers, and lie if they happen to be a CEO putting out a press release.
No, CEOs are not expected to lie - that's very bad business, generally. They can selectively focus on aspects of the business that make them look good, and dodge questions they don't want to answer, but flat out lying as a CEO is wrong, and destroys your company's and your credibility.
