This is a non-Veilguard post but it is a Solas post and a Varric post so buckle in.
Background: I joined a Veilguard Discord server because I'm insane, and we were discussing Cole and the whole choice to make him a Spirit or more Human, and it almost got into an argument but thankfully it figured quickly, but I was still thinking about it because something about it all rubbed me the wrong way. A lot of people lamented their choice in making Cole more Human or cheered that making Cole more Spirit was the correct choice because of Solas' own regrets and pains that came about from him gaining a mortal body.
Subjectively I have always chosen to make him more human, but I guess me choosing as a player is different from within the context of Inquisition. In DA:I every choice you make has consequences, sometimes trying to backpedal out of a choice once you're far enough in will result in you not getting your way because that's what it all is, Choices and Consequences. As much as the result of Cole's change is on you the player, it's really a Consequence of your favoring Varric or Solas' method.
Solas' entire view of Cole's predicament is colored by his own negative experience of having a body and living in the physical world, waking up to a physical world where the Veil was created just amplifies that regret in pain, every instance of him trying to help with his Wisdom becomes something worse to him personally (All that Wisdom and he can't help himself) but with Cole he actually can help! He can fix this, with not only Wisdom but experience! He's become a person, he doesn't like being a person(and then he does because of the Inquisitor, I feel this is true romance or friendship), so Solas knows that Cole can 'return'(made) more Spirit and the confliction will end.
Varrics positions, his view, I feel is colored by the people he couldn't help, the ones he couldn't help get their revenge or solve their problem in time in a way where no one could get hurt (Cole literally reminds him of Anders just in reverse) And this time, Varric knows better, he knows how to fix this, he knows how to not blow up the Chantry, he can fix it this time. (This time the love will be enough!!)
Objectively, both are answers, I don't think either of them are right, because it's one influence over the other, but a choice has to be made otherwise he'd become a demon.
Solas and Varric are having their idealogical battle(custody battle) over which direction Cole needs to go in to avoid binding or demonhood(which college to send him to). The added layer VG adds to this and every banter Solas and Varric have is also fascinating, because outwardly it's an Elf and a funny Dwarf fighting over the tall awkward Human child, but after VG??? After those regrets??? Girl...
But I feel that reducing that scene to Solavellan at times is... disingenuous, when really, it's a Solvarric scene of we're being objective.
This is THE custody battle of all time. (My weed kicked in bear with me)
Solas' version of his world doesn't exist anymore, the world with no Veil and spirits essentially pillaging the bodies of the Titans to gain bodies doesn't exist anymore, the first victims of what the Elvhen did calls him Chuckles, a demonym in true friendly jest to him, it's the first thing Varric calls him when he reaches out to talk to him at the beginning of Veilguard, up until that point he calls him Solas, the Dread Wolf, Fen'Harel.
Varric is a result of years of time happening to the version of the World Solas brought about. Its...it's like God is talking to a creation of his that has every right to hate him, to want to desire to go back before all the bad shit, and instead Varric says, okay, get the anger out, how do you feel now? Empty? That's okay too, take your time.
Solas is a weary traveler ready to end it all and Varric is the equally weary traveler who says, tell me about it, and then talks your ear off so much you start believing in the world again.
Basically, Varric's method is to embrace the history and the scars, embrace the hurt and once it's done, get something to eat. Varric forgives but doesn't forget, his plan has Cole let go of his anger in the end, but Cole will remember the hurt he felt, and inflicted and so will the people he inflicted them on.
