Aiding the darkspawn defeats the purpose of your whole entire journey in origins. The whole reason for so much corruption in the world is because of the darkspawn. You might as well shoot yourself in the head if you think negotiating with talking darkspawn is a good idea. It really is mindblowing to me to see people wanting peace with them.
Really? Because I thought it was to end the fifth blight. Which I totally already did.
That's what I thought too. I thought of darkspawn were dangerous because the taint makes them mindless monsters incapable of intelligence, morality, individuality etc. They can't help seeking out or corrupting the Old Gods, which in turn can't help wanting to destroy the entire world, because they're just following what "the song" of the taint tells them.
Free them from being mindless monsters and giving them the chance to learn morality and individuality, allows them the chance to be just as peaceful, reclusive, and self-governing as any other race.
At least, that's how I see it. I must confess my city elf saw it from the perspective of she can't stand her people being negatively stereotyped and generalized by humans, and felt she would be remiss if she did it to darkspawn. She felt painting them all as "Rah! Rah! Darkspawn evil! Darkspawn dangerous! Darkspawn must die!" wasn't much better than "Elves = useless, elves = vermin, elves = thieves and troublemakers, elves must be suppressed, driven out or killed."
With that said, my City Elf's not stupid or a bleeding heart. She knows darkspawn are potentially dangerous, and intelligent thought can make them even more deadly than mindless monsters since they can still be evil, chaotic, destructive, and use their cunning to spread their taint in ways mindless monsters can't. That's why my character wanted to keep talking to the Architect and make a more informed decision later.
Neither she nor I realized the credits would roll after you kill the Mother without giving you a chance to make an informed decision then, but there's no taking it back now. Even if I did, I just don't feel fully comfortable painting all darkspawn as "EVUL MUST DIE!!!!" and exterminate every one I see because I wouldn't want it done to me and mine, especially I and mine are able to know and choose better.
