The Architect is pretty irredeemable. He wants to the darkspawn conflict via genocide. That's not particularly different than how the other darkspawn operate. He just happens to have a more refined view than murdering everyone by stabbing them with pointy ends. He caused a blight, and DA:A is all his fault.
I don't think he's different from a darkspawn at all. He can just think.
There is more to The Architect than you see of him in Awakening. Let me explain this a bit. The way the Architect sees it, one of two things will happen, if noone comes up with a plan:
A) Eradication of all darkspawn - everyone above ground (+ dwarfs) wins.

Eradication of all living beings and corruption of the environment during a successful blight - darkspawn win.
The Architect obviously does not want A to happen, but he does not like option B either (which makes him different from his fellows). He had two plans, two failed attempts to stop it all with preferably minimal bloodshed. In 'The Calling' he elaborates on his intentions. So, seriously, given his knowledge of A and B, do you really think he is just like the rest of the darkspawn? He does have a point, doesn't he?
On a side note, I was surprised how hard most characters (Grey Wardens) in 'The Calling' avoided to reason with him. Instead they appeared to follow the same stupid formula: If it's a darkspawn, even if it talks and reasons, it must be bad and be killed. If it has plans I disagree with, I don't reason with this oviously reasonable creature (which too merely tries to stop blights), no, I rather try to kill it! Grey Wardens, at this point, appear to be a rather dumb bunch of war mongering soldiers without any real intention of stopping the whole thing. Instead they dim-wittedly prefer waiting for another blight. To me it makes more sense to start talking with this thing, because it is an opportunity, but obviously it has to happen secretly, because of the average Grey Warden's incapability of understanding more than just the next darkspawn kill (because they're evil). Someone with A and B in mind and knowledge of the Architect has to make somthing of it. Merely drinking your enemy's blood and looking for a every possible fight with it just doesn't cut it in the long run.
