@Xilizhra: Yes, you were trying to say that the Templars were probably more reasonable... I'm saying they're not.
Regardless of how I view the mages... I'm not Pro-Templar. I think both sides are very wrong.. and like two very wrong sides (even two very right sides during wartime) - they often do very destructive, short-sighted things in the name of dehumanizing "other".
This wasn't a templar order interested in simply corralling mages again... I feel this was a templar order seeking to maximize the damage on all fronts to mages and magic after Adrian tricks the Circles and Cole murders Lambert (justified or no).
Everything they've lived for is being torn down - I don't imagine them acting rationally at all.
NOTE: I do think there's a sincere level of demoralizing strategy in openly destroying the repositories of magic that were the Circles. Mages would be acutely aware of all they are losing for their freedom... and not a small amount, I believe, would regret that and doubt their decision.
NOTE 2: This is a pretend war... with sides we cannot really know anything about because they cannot be researched... or studied in any sufficient way. So at the end of the day... I have no real commitment to being "right" - I just think real history errs on the side of wanton destruction during wartime.
