I think you are completely missing the point.
Did he say he wanted to restore the world exactly as it once was, with no changes at all, and so he could restore all the "gods", make slaves again, and proves himself as a god to everyone ???????!!!!!! No! All he said was to torn down the veil!
He saw the people of this world to be far removed ( and lesser) compared to his people. he is entitled to his opinion (one that has mostly changed), and I would not discuss it here.
Did he showed a specific intention of going about and destroying other cultures, and shoving the Elvhen culture down their throat to mold them into mindless slaves? No. He is of an inquiring mind. Even if he dislike other cultures he took the time to learn them. I think he is capable of showing the minimum courtesy and respect of letting other cultures be, if he succeeded.
And regarding the change of the cultures. Here is a fact: Cultures change. Cultures change in respond to the environment. That happened in Elvhen, why can't it happen again with the current (elven) cultures? This is not trying to correct one sin with another. This is to change the environment so that something of fluid state can reshape itself. Even with the veil still intact, many elves are following Fen'harel. Are they not showing an intention to change already? Is the elven culture not changing already? And for the humans, have they not changed the culture drastically over the past thousand years? It's not that you give a culture time for it to grow, rather, cultures emerge in time. Even if the veil is torn down and all elves get to know the old way, does that mean they would be exactly the same as Solas remembered elves? I think not. The elves already bring about them so many new elements. The elvhen culture will change, and that is not something Solas can control, god or no god.
And Solas, of all the elves of his time, knows the best about the corruption of his world. Not just of his world, but with power and society in general. I don't think he intend to make himself a king to rule over the new world. He said only to torn down the veil. Frankly, I think doing that would not change a thing about the potential misery or corruption that existed throughout history. It is just a world of a different form, one where the elves would become healthier and stronger. And I think that is all Solas wanted at this point: to create an environment where the elves are restored to their previous strength and therefore have an edge.
Whoa, please don't think of my words as anything personal - I just see this from a completely different perspective. I did not mean to argue with you, just discuss more stuff about our bald egghead.
Yes - he wants to tear down the Veil. And he is perfectly fine with sacrificing all of modern Thedas by doing so. He says to the Inquisitor that he drawed them to where he was so he could save them at least for now. He says he intercepted the plan of the Qunari and stopped Coryfish because he wanted peace for the last couple of years of modern Thedas.
I never said that Solas isn't compassionate - I think that is his core problem in being a 'villain'. He cares way too much about individuals being free and also being free from suffering. Solas has a lot of flaws that make him more 'human' (or elven? heck I don't know) than he could potentially stomach. He wants to be wrong, yet he sees no alternative. If the Inquisitor CAN prove them wrong, then they should - prove that there is a way to keep modern Thedas alive and well. Solas himself, though, thinks that isn't possible and instead of facing his weird way of thinking, of behaving like erasing a mistake can actually work, he's rather indulging in the fantasy that Thedas isn't real after all. And that's bad.
Of course, Solas cares about the little Qunari baker who puts a small secret into every loaf that she bakes. But that's just it - he doesn't care on a grand scale, at least not enough to overthink his strategy and work with the Inquisitor together to built a better future for Thedas. He did try to teach the Dalish his way of thinking, but they wouldn't listen to him - why should they? Some random apostate hobo just turns up and tries to take everything that they still have away. He'd strip the elves of modern Thedas off their already shallow culture just to establish his own that, well, is right, but doesn't help the fact that he would basically put the Dalish into a situation in which he finds himself in: Stripped from everything that you thought you knew.
Uhm...I made that point about cultures changing? Like, that is exactly what I talked about: That cultures change and that Solas does not have the free will to decide who's culture lives and whose culture has to die. The Dalish HAVE a culture. It is built on false beliefs, but Fen'Harel does not have the right to strip even this shallow culture away because he believes that he alone has to decide what is right or wrong.
The point that I was trying to make is this: Solas has NO right to shape the elven culture, yet he tries anyway. That's why he is behaving like a god. Solas sees modern Thedas, sees that it isn't HIS culture, isn't the world that HE remembers and decides that nothing in Thedas can be real and that he can just take everything from the world away that was built over a thousand years. Well, that was his PLAN anyway. The Inquisitor proved him wrong - but he is still determined that it is the only way, that his people and his old culture is worth more than the people currently alive and because of this, modern Thedas has to go. He's taking no joy in this and I believe that, but Solas is STILL willing to decide the fate of all of Thedas without actually asking Thedas if they even want this erasure.
I believe the elves are following Fen'Harel because they think he will bring the change that they wanted so desperately for the last few hundred years. But Solas is a 'the end justifies the means' kind of guy - he used the Inquisition for his own plans (to get back the orb from Corykitten), he uses his agents to further his goal and he also uses the elves for that same goal. Solas is building an army. If he can only achieve his plans by deceiving countless of modern elves, then he will do so, because, well, they aren't 100% real anyway. (That does NOT mean that he likes it, of course.)
Nah, Solas doesn't want to be king. He actually believes he won't survive his Matrix like restart, anyway. But he is still playing god. He ALONE believes to know what is best and though he has a huge amount of knowledge, that does not give him the right to doom millions of people, only to raise back up his own people. He doesn't want an edge for the CURRENT elves of Thedas, those can die because he sees no way to save them - he wants to strenghten HIS people. HIS alone. He said countless of times that the modern elves aren't his people. They are just like every other race of current Thedas: Worth just enough to give them peace in their last years, but not worth enough to save.
