I don't believe that at all, in fact my first two playthrough's I struggled with deciding his fate at the Landsmeet (one time just flatout ending him, the other time doing it after Alister's freakout) because it becomes so apparent that he's the whole 'paved with good intentions' archtype.
When you meet him at camp you don't know what to make of him. He seems ok other than the shifty face they give him, and he sounds very reasonable when coming up with the war plan, but when he ditches out during the battle in Ostagar you're convinced he's the devil. The two or so little cutscenes you get while playing the game seem to reinforce that, then you get to Landsmeet.
It becomes very apparent that he wasn't trying to off Calian just to get the throne, in fact looking back he did everything he could short of kidnapping to keep him off the front lines. At the Landsmeet he really knows what he's saying; as a person, he's kind of crap, as a ruler in wartime you don't want your buddy, you want an SOB who will do whatever it takes to keep his people alive and that's exactly how he approached it. Sure he wasn't perfect, his downfall was of course a total ends justify the means approach coupled with his lack of respect for the Grey Wardens, Orlesians, and belief that the sky was falling (a true Blight).
I fully expected to walk into Denerim to kill the Devil and he actually made me regret doing it by the end of the Landsmeet. It was a very good play on Bioware's part.
The Morrigan romance is another one I feel was done well, but it's just simply incomplete. If this was it, we will never close these threads with the originating Warden, then we were cheated plain and simple. If this was the hook for DA2's setup, then it could be damn near masterful. You take a Witch from the wilds who only looks out for herself, and over the course of the game you get her to open up and actually care about someone other than herself (I thought the 'Even if there were 100 Grey Wardens in the keep tonight, I'd want [The Dark Ritual] to be with you', before the final battle to be really telling) and to even question if her ways are the right way of doing things. Sure, she never came out and said she was wrong, but you can't tell me the constant stumbling here and there in conversations and regret she shows midway through when she knows what she has to do, but knows it's going to suck to do so, hell, even asking for help when the Morrigan you met at the beginning of the game would have rather charged in blindly and just dealt with it showed growth.
That does hit the snag though. Everything through DA:O was amazingly done, even the total sucker punch at the end, and end's on the low note of you giving up everything to track her down. If there is closure in a future game (and has been pointed out by other people, with how Bioware does choices, you could have a 'selfish good' closure, or a 'I love you but you have to die' kind of meeting), perfect experience, or they can totally drop the ball on it.

Example: Loghain is not meant to be an obviously evil figure. According to Dave G he simply thought the battle was unwinnable and decided to save what he could.
IN THE GAME: All Loghain needs is a moustache to twirl. The second you meet him he's obviously up to no good and acts COMPLETELY evil up until you recruit him, where he basically becomes a completely different character vs. what you've experienced in the game to that point.
