I bet you'll be at odds with her about mages, though, JB. Just an empty wager.
I had the same thought. I think that this:
“Doing something for the ‘greater good’ makes her angry, because she thinks that's shorthand for ‘let's hurt people who don't deserve it because it's easier.’"
is how she'll describe the Circle system; locking mages away and pretend they don't exist is just "easier". She'll probably oppose politically powerful mages like Vivienne but include the rank and file of mages into the group of the powerless she sees as being hurt by the actions of the faction leaders.
Meanwhile, I will still hold true by the notion that all mages must be isolated regardless of their level of magic or secular authority.
