@Illyria: No need to apologize. I don't take offense at very much. You're passionate and that is good. It is only "wrong" - I would argue - when someone is trying to censure others passions that oppose them. You were not trying to do that I don't feel.
I honestly did not see anywhere where Solas genuinely questions where he has the right to kill all of modern Thedas. All he says is: "I have to." For me... that's a load of crap. And certainly not an answer you give someone you respect or call a friend.
Sociopaths can logically know they are supposed to "feel bad" and are capable of saying: "I feel bad." when their actions say anything but.
Solas isn't even passionate like the Doctor tends to be when he goes off the deep end... he's cold and calculating and rational and still decides killing everything for his own agenda is perfectly reasonable. If I recall correctly - he's pushed pretty far when he becomes Timelord Victorious (throughout the entire season if I recall correctly).
Also - if I had seen Solas do one thing like the Doctor has done in his many long years in story... to sacrifice himself for other people - then perhaps I would see him as varied. Appealing to some ancient tale that is told to me by someone who has been lying to me since I met him... where he conveniently plays the hero... is not enough for me.
Again... psychopaths and sociopaths are amazing liars and often convince others they are the "nice, quiet neighbor next door."
- The Inquisitor would not need saving if Solas hadn't tried to kill him/her first. It's even worse (for me) that the Inquisitor was just "collateral" damage.
Also... nothing that was done to the Inqusitor was done to him/her for "the greater good" - it was simply Solas taking advantage of opportunities that arose after his initial plan when awry. DA:I would not have happened if Solas wasn't trying to destroy the modern world.
NOTE: I am currently good friends with Solas with my Lavellan playthrough.... "I" know what Solas is going to do to my Lavellan... and I know that my Lavellan will be pretty crushed that a person he thought was his friend does to him was Solas has done.
It's a shame... someone was saying how Solas doesn't have someone to ground him.... my Lavellan is standing right there. It is Solas' fault for deciding to remain detached.
If I carry this character as my main into any story where Solas is involved... he will try to stop Solas without killing him, but he will never see Solas as a friend again.
My friends don't lie to me their entire lives... put me in danger for their own agendas... and then require me to drag them from their own self-destructive tendencies. To me... that's a poisonous person only dragging me down.
