So to summarize: You condone Anders' act of terrorism, because he as an illegal Apostate, who had no business interfering with Circle affairs, weren't listened to by the powers that be.
You know that whole "We don't negotiate with terrorist" policy that most governments use?
....you got it all in so many wrong ways ! for the first part ,it have nothing to do with him being illegal or apostate or anything at all regarding him . he did it because he witness the violence acts and abuses on the mages by the templars everyday more and more ,templars who should have been the law ,instead they used their power like that alric to condam innocent mages like that girl into tranquility so they could use them in the so many ways they want , if this is not terrorism itself .
and yeah your right ,he did had no business inteferring in the circle affairs, do you guess who's business was ? the grand cleric . what did she do regarding this business ? nothing . keeping an eye over all this transgration of law by the law itself , and bieng above the commander of the law itself , she kept silent. silence over the days ,over the years , trying nonetheless to reach for her and speak sense to her , but even her couldnt do anything to help those people .
i think this is the part you didnt get.
after that Anders was not claimed as a 'terrorist' yet when he was still trying to speak to the grand cleric ,when he was still writing his manifesto ,when he was still helping people in the undercity for free.
that part too you forgot. now try to rethink about what i say above if you want .
