I'm not sure I'd be quick to dismiss this as a "non-apology." I think he's indeed smart enough to know what he did was wrong. But I think as a writer with hubris, he can't refrain from asserting himself in some way in a written statement.
When I first read about what he did, I actually wondered if he'd have the guts to apologise at all. This is by no means perfect, but as flawed a character as he may be, I can't bring myself to hate him.
