Well, they were still describing him as hero, Arthur still didn't know he has magic, there still was enemy behind their walls etc. It seems BBC were simply trying to use concepts of previous seasons as long as they could.

And Merlin's insanity: Arthur, Morgana or Uther could change but with him it's a bit different. I was referring to actual psyhological disorders. He have destiny of protecting Arthur and Camelot, cares for them all, but he have more than serious reasons for turning against them - Uther exiling his father, Freya's death, Camelot politics, the way everyone treats him being the most important. In other words he has enough reasons for both saving and destroying Camelot. Problem is that we see only Merlin's lighter part(which is understandable in a way - telling anyone his secrets or about his mistakes couldn't end well). Gaius knows, but it seems he only knows and cheers up a bit when Merlin is sad. And there is Dragoon, who is actually expressing all the negative he can.

Besides, while others have harsh life, Merlin's could be called fatalism inducing and moral suppressing.
