You're Pro-Templar and want magic to be completely eradicated? I would love to hear your thought process on why. I personally am Pro-Mage and want all the (current) Templars to be eradicated, along with The Chantrys' extreme influence. So, by definition, we are complete opposites. I think we could have quite the debate. But, perhaps this thread is not the place. 
On the other hand, I'm almost completely neutral. I have very little sympathy for either side in DA2. 99% of the mages appeared to have neither a sense of self-control, nor any use for gratitude (I'm looking at you Grace). Orsino seemed like such a nice man until his involvement with Quentin came out, I was pretty glad I got to kill him after that.
The templars were generally arrogant and abusing their power (Alrik) or incompetent and cowardly (Thrask) and Meredith was obsessive even before she became cuckoo.
If there had been a way to say "screw you guys, I'm going home" my Hawke would have sailed off to Ferelden and left them all too it. As it is I always end up siding with the mages because I can't personally justify killing them all as a result of Anders' actions.
