Maybe some of the people who don't want him dead can help me out? I'll admit up-front that what I've seen about this DLC is pretty much a worst-case scenario for me, and I have no intentions of playing it. And the truth about Solas is worse than I feared -- that is not part of the "worst-case" scenario for me, but looking back at the main game, it colours so many scenes (even ones he is not directly involved in) with a lot of bitterness and anger at having been used and lied to like this. While I kind of liked Solas-as-Solas despite his very obvious flaws, I was
really worried about Solas-as-Fen'Harel, and now can't for the life of me imagine how we're supposed to consider him as anything other than the monster he protests he is not. If anything, his kind of evil is far more insidious than the likes of Corypheus or some Stereotypical Moustache Twirling Villain. So I'm asking honestly ... how am I supposed to salvage my opinion of this character to any degree?
Specifically, I'm asking from the POV of someone who played a non-elf non-mage and always had sub-zero interest in "romancing" him. I liked to think (before the reveal with Flemeth/Mythal) that he and my Inquisitor had a sincere friendship that, while not as close or easy as her platonic love for Cassandra and Cole, was nonetheless important to her. As a non-mage, noble-born, devout (but open-minded and devoted to the truth) Andrastian, partly templar-trained human who made a lot of "big" decisions he disagreed with, she probably embodies a lot of what he is in inclined to particularly dislike, and they had a bit of a rocky start. Their friendship was hard-won and slow to build, but no less valuable for that -- in fact, she came to rely on him as an "outsider's voice" to provide an important difference in viewpoints that, despite all attempts to be open-minded, might otherwise go unnoticed by her and Cass and the advisors. Basically, she's a lot like Cassandra, with a bit more political acumen, a growing fascination with spirits, and a slightly lower tendency to throw punches when she gets p*ssed off. 
I supppse some might say that this hard-won friendship based on what I thought was genuine mutual respect not despite all their differences, but based partly on those differences, on being able to disagree quite strongly at times while still trusting each other to act with thoughtfulness and compassion and integrity, actually makes my Inquisitor a strong candidate for being able to shift Solas' views. If the friendship and respect were sincere on his part, then coming to view her that way was already more of challenge to him than beginning to feel kinship for someone who is a lot more like him.
Thing is, that is a pretty big "if" for me to believe, all things considered. And I just ... didn't see anything sympathic or tragic in the talk with him. If anything, it just kept getting worse. Maybe playing it instead of watching it would have felt a little different, but I don't think it would have changed my mind much. Part of Solas' "legacy" until that point was that he and Cole are the reason why my Inquisitor came to see spirits as people in their own right, why she wants to do what she can to make people less afraid of them and interacting with this world safer for them. I imagine that is what first truly broke the ice between her and Solas: they bonded over her newfound desire to learn more about spirits so she could truly help Cole feel safe, welcome, understood and cherished. And then Solas pretty much confirms that no one in this world is a person in his eyes -- that was a real brutal gut-punch.
Cole still feels for him, clearly, and usually I'm so partial to my most compassionate friend that I will take his reaction as "proof" that the person in question isn't wholly beyond redemption. Until this point, that is what kept my hopes up for Solas. Now, hearing the full ugly truth from Solas' own mouth, even that is not enough anymore.
Long story short, and sorry for the wall of explanatory text: what can a player and a character who are NOT inclined to think Solas is the bee's knees (be it because of "romance" or for other reasons) do to not hate him now?
