All the Architect ever did, throughout all of the game was to try and free as many Darkspawn as possible from the Old Gods. THAT is the action I'm judging him by. That he has attempted to kill me is a non-issue. Zevran and Loghain both tried to kill me and they still became trusted party members.
And I don't think the Withered was exactly planning on sparing Varel, we just sorta interrupted his execution 
What!?!?! Zevran and Loghain aren't corrupted and tainted darkspawn. The Architect is a mutated darkspawn. He's not even human, Zev and Loghain are. Majorly
BIG difference.
What is a Grey Wardens job?
To kill the darkspawn and end the Blight no matter the cost. We ended the Blight but our job still isn't done. Just because the ArchDemon is dead doesn't mean a Grey Warden's job is done. It will never be done as long as there are darkspawn around. Doesn't matter if you made them stronger or not. Doesn't matter if they are no longer forced to seek out the Old God. THEY ARE STILL DARKSPAWN!!!! They are still a danger to the world.
The Architect never once comes right out and says there will never be another Blight. All he wants to do is free his brethren from the Call. That doesn't mean they won't stop looking especially if the Old God can help them take over the surface.
Letting the Architect live is an easy out for the Warden. When you're making that decision about letting him live are you thinking about yourself or are you thinking about the rest of Thedas and what letting him live could cost in the long run. He does not care about the surface world.
All he cares about are freeing his brethren and damn the consequences. And that's all you doing by letting him live, damn the consequences
