[@McHaggis]I liked DA 2 a lot more my second playthrough. Which was a month ago. (Didn't like it as much when I was 16, 19 now.)
And I supported the Templars as a mage. Mostly because it is hard to feel sorry for a group the pretty much does terrorist level shit because "We don't want to be weapons, so let us be weapons, by becoming super weapons, aka blood magic." 

Like the Thrask story arc? I supported mages for a while, I stopped really bad Templars and even spared a "Blood Mage" from execution. I respect Meredith to a point where she is a patriotic and wanting to prevent outright genocide, but when you completely bomb a neutral party simply because of intolerance? After you did nothing but try to help the "Oppressed" ? You just lose sympathy because they go to extremism. 

So yeah, I support the Templars in that situation simply because they just wanted to protect the city from Mages losing it and attacking everything on sight. Yeah, remember the First Enchanter? He turns on you really fast regardless of decision. 
Meredith only turns on you because of the Red Lyrium Idol. If she was without it, she would not have killed you for trying to help enforce the idea of law and regulation. 

Think of it this way. If everyone tries being extremist, how far will others go to make security to protect neutral parties from the one? The Neutral outweighs the one. 

As for Fenris? I wanted to like him when I was younger. (Thought I was gay at the time due to certain friends trying to coddle me. I'm Asexual as in I just do not care, if you are cool? Then that is super.) But ended up hating him due to his broody nature.
