Laws at made because of what people might do, its just a fact. We outlaw murder because people might murder. We outlaw rape because people might rape. And violating the law once shows precedence you might do so with other laws, which is one of the main reasons arrest records exist. You can pound your fbis all you want about the law being unjust or immoral. But what I keep saying is thst you need to demonstrate how it is wrong for all, which I dont see you doing.
We make laws based on crimes we may commit, it's true, but we punish people AFTER they commit the crime, not before, and not because they fall into a category that 'might.'
Mages may run because they simply want to spend time with their family, have the opportunity to be with a girl like in Act 3 in Kirkwall, or because they feel life on the run and being killed is preferable to conditions in the Circle.
Mages live in conditions in the Circle that are not designed to help them grow as people and to emotionally develop to be stable members of society. They are treated as disasters waiting to happen, many of their 'care-takers' don't even see them as people and emotionally distance themselves from the mages because of how they're born, and there is no oversight being enforced upon the templars who abuse their authority over mages.
Talking about laws is all well and good, but laws completely lose meaning if the reasons they exist are forgotten, are not followed through on one group or another group, or are too heavily enforced that you actually end up creating just as many problems as you hope to prevent. The Circle system, at least to me, seems to be a case of all these. The rules of the templars make clear that their duty is not only to protect the world from mages, but mages from the world as well. Most templars and seekers seem to have forgotten that part of their job based on game-play and the novels. The laws that exist to protect mages are not enforced by the Chantry or the templars when it comes to punishing their own people. Even in Ferelden they had to catch Lily in the act, otherwise she wouldn't have been punished while Jowan would've been. And some places, like Kirkwall, the rules are so heavily enforced that the mages are punished simply for talking to people, and it's not an emotionally safe environment.
Should a mage escape such a place, but goes on living their life in a way that doesn't hurt anyone, then there is no moral authority that justifies their death, even if the law allows it.
In the eyes of the law, you are punished for what you do, not for what you are. And it should be applied equally to all people, not just heavily on one side and not so heavily on another.
