How little do you value qunari lives? Is one Charger worth more than 1000 qunari? 10,000? How much do philosophical differences devalue someone?
Quite a lot, apparently. I've read comments 'round here like "I'd kill every Qunari if I could". When I asked, "even the defenseless and children? (because not every Qunari is some duel-wielding holy warrior)" Radio silence was my reply.
It's much easier to speak in absolutes and commit atrocities when one views things simplistically, in terms of black and white. There's good and there's bad, but never an in between.
Qunari = the other = bad (kill them all!)
Mages = the other = abominations = Saarebas (chain them up!) Apostate (make them tranquil!)
It's kind of ironic that the "no good Qunari but a dead Qunari" tribe don't realize they sound even more radical than the staunchest Qunari, who believes there is no way but the Qun and everyone must submit to it. They can't possibly comprehend that even amongst the Qunari, there will be conflict as to what the will of Qun dictates. Some will be expansionists like Gaspard. Others will believe the Qun wills that they war only when necessary to protect their people.
The difference here though, is that we know for a fact that the Qunari will eventually invade and resume their crusade once the timing is right. It's inevitable.
The idea that an alliance with Qunari is wrong because they'll eventually invade - perhaps 10 or even 100 years from now - is laughable. War is an inevitability in Thedas. Orlais will war with Ferelden again someday. But does that mean it was folly for my quiz to broker peace between them while she could?
If any Inquisitor thinks that way, then they might as well swan dive off the ramparts or hand in their sword. No reason trying to do good in a world that's ultimately doomed to blights and war, is there?
That said, my Inquisitor is a pragmatic, don't throw the baby out with the bath water sort. She didn't banish the Grey Wardens and she sent Thom to serve them even though she personally wanted to take his head. There's no way she would sacrifice an alliance that would serve to bolster the Inquisition's power in the fight against a wannabe demigod to save a group of paid mercenaries who couldn't hold their own when it was crunch time.
She knows what it means to be a mercenary. It means your life is expendable. And if you can't hold your own? Your life will be short.
