And what would it change?
What does it even mean "mages to run circle"? That there would be no templars, like, at all? That they would be able to be just human beings like everyone else, and circles will be like Hogwarts? There will be no such thing.
But allright, let's say the Chantry will agree (but actually, what the hell, we know they won't) and how long will it last until they shackle them again when this will be over and human nature will surface again?
And giving the current situation, they either gonna blame Tevinter regardless or Tevinter actually brought upon the world all this ****. Either way, I don't see how they can agree to give them more freedom now or shortly afterwards. Or give it at all. The Venatori (and also, Anders) now is a shining example for them why they actually shouldn't do it.
Also, I don't think she's "evil". It's such a childish value. She's simply a troublemaker and potentially a threat, she wants to do something I strongly oppose. I didn't even think to raise my hand against Wynne (or Fenris, or whatever) or any other companion so far, for the record, no matter what. But Vivienne may give me a cause to do it because unlike the others she has a real power that can make a difference.
And I also don't like being toyed with and being used, so if she'll try to she'll pay for this. I think it's pretty fair.

But seriously, don't like - don't read. Just like most people do.
