HIDDEN SPOILERS:
I remember being angered by the thought mechanism of the game. It's awfully convenient how you NEVER get to read the true thoughts of the killer. I can buy that his personality would completely change after the reveal (because he's clearly a good actor) but it's impossible to keep inner thoughts secret.

That's a good enough explanation in the context of the game, and had the game included that, that would have satisfied my curiosity and not made me feel like something was missing. Would it have killed them to add another 30 seconds to the ending showing a few quick cuts of what you described?
Anyway, I noticed that no one's discussed The Taxidermist DLC in this thread yet. For being as short and oft criticized as it is, I really liked it. The sense of dread is well defined and the short run time makes repeated playthroughs to get the five endings a snap.
I can see why not including that explanation in the game is annoying. At the same time, I'm a bit glad they did not include it. I think it's nice to actually have to figure things out. Again, it can be annoying, but as someone who enjoys a good mystery, I actually enjoyed pondering why those things happened 
I don't have internet at home, so I never got a chance to play the Taxidermist episode. I was hoping they would release it on disk eventually, but alas no avail...
