I would rather die as the world burns in raw chaos than to join the Qun. Better die free than to be a drone.
You know, there is one reason why this argument will never phase me.
We've interacted with a lot of qunari at this point. Sten, Tallis, Bull, Arishok, Ketojen, Arvaarad, Gatt, Viddasala, so on.
And none of these people are mindless drones. All of them make decisions, moral judgments, act of their own initiative. They may use the Qun as a moral guide and code of social conduct, but they don't all come to the same conclusions and act in the same manner or have the same thought processes.
Arvaarad was a tool, but no more so than several of the templars we meet. Viddasala was a mad woman and a fanatic, but there are no shortage of those outside the Qun. Ketojen committed suicide for his beliefs but that's no more extreme than circle mages volunteering for tranquility. Bull will turn on you if he's loyal to the Qun, but you're the guy who ordered him to let his closest friends die alone for a hill; I'm pretty sure that's a little more personal than he admits at the moment.
And yes, they want to invade and convert everyone, but so does the Chantry. They've committed two genocides over it, in the Dales and in Rivain. They've gotten lazy about it in the modern era but their belief still holds that the Chant must be sung from all corners of the world and it's only a matter of time until a Divine lights a fire under them for it. And let's not forget that while the Qun will "reeducate" you, the Chantry will kill you for heresy. Just a matter of one being a little lazier about it than the other.
So you can try painting it with the simple, Orwellian nightmare brush that the Qun haters like to use, but from where I'm sitting, that isn't the picture the evidence paints. I'm not saying the Qun is perfect by any stretch of the imagination and I, personally, in real life, would not want to live under it. But I can see how a reasonable, sane, and intelligent person living in Thedas can take a look at it and decide that it's a life they'd like to live.
And outside of that; I, in real life, as a gamer and fan of the series, cannot think of a more satisfying ending to Solas' story - again, for me, from my perspective - than him being defeated by the Qun. He likes the Inquisitor. Or at least he respects the Inquisitor. If he's defeated by the Inquisitor he's going to accept that with grace and dignity, if with sorrow. But he hates the Qun with every fiber of his being. If he's defeated by the Qun, for the Qun, he will rage. He will seethe. He will spit his last breath at us for hate's sake.
And I would savor every moment of it.
I'm not saying it should be mandatory. I said from the start it should be entirely optional. But it would be an option I would take because it would be the only way to make the confrontation between Solas and the Inquisitor actually satisfying for me. I don't want to have to endure Solas going out like Loghain if you choose to execute him. I want the option to have Solas go out like Howe; cursing us in impotent anger.
Or we can just have a game without the Inquisitor as the protagonist and I'll be perfectly satisfied with that.
