I hear you on this, and I don't think I would act how Lirin would. However, I think it would be a little willfully obtuse to say that Lirin isn't fighting back. He's hiding and aiding a general that is seemingly crucial to the Herdazian war effort (the only other one we've heard of so far). I believe that Lirin thinks he knows his place, as a surgeon, and is doing his part to help the people. He isn't willing to pick up arms himself and fight, although he won't stop others from doing so (except for Kal).
