I judge him based on what i see is someone who fought fake gods and yet behaves just like one, someone who would sacrifice just about anyone to accomplish his self-imposed quest, someone who destroyed the world once because he chose to (he made the veil after the Evanuris killed Mythal, not before. He put his precious People to the sword because one person had died), someone who will try to do so again, change the natural laws of the world again, because he has a sense of entitlment that only someone who thinks hismelf a god could have
Whoa whoa whoa, slow down. He didn't make the veil just because Mythal died. He implied that the remaining Evanuris were going down a path that would destroy the world, and that creating the veil was the best option he had to stop that. It wasn't just about Mythal. That was just what got him to really start fighting.
Yes. Genocide is evil no matter how you slice it.
I... disagree, bad as that sounds. For instance, I don't think Shepard sacrificing the geth (basically genocide since they all die) to stop the Reapers is evil, and I don't think it's necessary evil, just necessary bad (understatement though, obviously).
Where we differ, based on another one of your posts, seems to be that you think acts are inherently evil, regardless of intent or circumstance and I think the opposite. I think someone's intentions are what make them "good" or "evil". Would you consider killing to be inherently evil? I don't, because I think self-defense is legitimate. Animals also kill all the time, are they evil? Intention and circumstance are key.
I couldn't care less to categorize the reasons of why some players may like him however call petty and ignorant those who categorized Solas as a self aggrandizing megalomaniac and a worldwide criminal just because his fans want to see him into another light isn't right either.
I was referring to people who were categorizing, so if you couldn't care less about categorizing people, then I wasn't calling you petty 
Yes we do. He says how his plan will result in the deaths of humans, dwarves, qunari, and even the modern elves all so he can save the remaining ancient elves.
We don't know that, absolutely. He's pretty vague about it. He says "even if your people must die" (emphasis mine) and "your world will end" (your, not the), but that could simply mean that your way of life and culture will end, because it will. I'm not disputing that many will die in the process, whatever the process is, but it's not clear if what he does will somehow directly cause everyone to keel over, or if the sudden change of the world will simply impact culture and way-of-life in such a way that many die in the ensuing chaos.
For instance, just imagine everyone suddenly becoming mages! People would kill other people because of their new-found power, or by accident, or get possessed... that could be the "burning in the raw chaos" he talks about.
Or you could be totally right. But we don't know for sure at this point.
