Vivienne's whole belief system is a bias because she talks as though she speaks for the best interest of ALL mages everywhere, yet from a certain point onward she lived a very luxurious and privileged lifestyle all-the-while being both a mage and a first enchanter and indulged in benefits and comforts that neither would likely ever dream of obtaining in a hundred years unless they manipulated and shagged their way to the top like Viv did.
Considering that she started off on equal-footing as any other mage in the Circle (excepting only for the fact that her Circle was functioning correctly, unlike the ones that we the players have seen), her privileged life just demonstrates how well mages could do for themselves if they bought in.
Given that, I would say she speaks for the best interest of mages better than any other one we have seen.
She certainly speaks for them better than Mr. Anders, who routinely ignored the fact that even mages abused in the Kirkwall Circle did not necessarily want to be free (Keran explains that the mage conspirators mostly want the Circle, they just wanted it working like it should... like the one Vivienne attended; Feynriel also says that other Circles are not as bad as the one Kirkwall and ordinarily he would be willing to go to one were he not stuck there).
True, she came from common birth, bur remember she stated that it was common for mages to be away from the Circle, all they had to do was ask permission from the First Enchanter. Yet any time we see a mage AWAY from a Circle, Templars seem to scream 'apostate' or 'blood mage' and get all swordy. Heck, in Awakening, I had a templar go after the freaking Queen of Ferelden because she had a hate on for a mage.
We have "seen" (using the term very loosely here) how many Circles, exactly? Two. A whopping two Circles. There are dozens of them in Thedas.
Two is hardly a representative sample of anything, yet even Bethany can be seen getting leave from the Kirkwall Circle of all places.
Quite frankly this is a silly thing to dispute. If Vivienne can say it was common for mages to be away from their Circle, how can you dispute her statement -- was she not there? Were you? Can you claim to know anything of her Circle better than her?
Again, I think you are trying to resist new information that stands contrary to your beliefs. Beliefs are the death of free-thinking; let them go.
Vivienne shows NO sympathy for her fellow mages. Instead, she's quick to assign blame. She writes off the whole Kirkwall incident as Anders, and nothing else. She seems to forget that the templars were JUST as much at fault. After all, mages can't beat, rape and murder themselves.
I kinda have made up my mind though, when I think about it. I do see the abuses of the mages, but when you continually kick someone when they are down, they are going to fight back. It's always bloody, and its almost always dirty, but they fight back. Viv, from her perspective, seems to think a strongly worded reply should be enough. When you've got broken fingers, and a bloody mouth thats missing teeth, that proves to be a tad more difficult. Even Cassandra and Cullen admit that the mages, while NOT innocent, were getting a REALLY raw deal. Look in the codex. You'll see under the Champion where another Knight Commander mentions the abuses at Kirkwall and how (depending on if you sided with the mages or not) Hawke felt that they had to step in. Ferelden was lucky, because the Knight Commander and the First Enchanter were old friends, but it wasn't perfect. Anders can attest to that. The White Spire? Yeah. Look at Cole's backstory. Calista and Martel handed over Avexis to Frenic...a Templar AND a Mother handing over a young elf mage to a blood mage?
My issue with Viv is that she dismisses what doesn't fit with HER narrative. Blame the mages, NOT the templars. Ignore that most of the mages felt backed into a corner. That even those who DIDN'T vote to join the rebellion got lumped in with the rest. Templars slaughtering ALL mages, young and old.
Okay, ... this post (as well as those by AedanStarfang) demonstrate a complete lack of understanding of Vivienne's position.
Here, let me help you out (warning: these facts might shock you)
Vivienne does NOT ignore/disregard Templar abuses --
Actual quote: "By all means, protest abuses by the Templars(...)"
On the Hinterland Templars, killing apostates in the fields: they "sully the Templars' good name"
Approval:
-- re: "The Templars made their beds" = Vivienne slightly approves.
-- "Templars aren't the solution" = Vivienne slightly approves.
-- Inquisitor disbands Templar order = Vivienne slightly disapproves (least of all disapproving companions)
Vivienne will admit the Circle is not perfect --
-- Says that all mages have had different experiences in the Circle, however, this is just a reality of life everywhere in Thedas
-- Singles out Kirkwall as a Circle that was not functioning right and condemns it
No denial of abuses within the Circle.
Vivienne never dismisses anything; her narrative is not what you think it is. She is for mages getting more rights and Templars being sat down. However, she rightly believes that thrusting mages into a war they cannot win will not end favorably for them, but only in disaster (that they can be saved from their impending doom courtesy The Inquisition is dumb-luck at its finest).
If she becomes Divine, I don't see her as a reformer...she's going to cement power. Mages get a better deal? Maybe today, but the Templars will chafe under her yoke. In time, they'll wonder why Orlais became Tevinter. They'll wonder how a mage became Divine, and think...is this what Andraste would have wanted? Is this what she fought for?
And we'll be right back where we started.
There is no point in hypothesizing over what will happen, the epilogue already told us.
If Vivienne is in good standing with the Inquisition and the Templars are being controlled, she puts down any rebellions within a few months (which is like no time, in a feudal age), makes detractors happy by renewing the Circle and makes mages happy by giving them greater power or by giving the Templars less.
It only goes bad if the Inquisition does not approve of her -and- if Templars are free of: lyrium and Seeker supervision and Inquisition conscription, but uncontrolled Templars were not a good idea to begin with (just like uncontrolled mages are not, either).
