Ah sorry, when u write "his" i thought u mean (beggar not yeorin's father) my bad.....
Hm....... maybe what he regreted the most was not killing aya's father, but killing him without trying other solution first...... like only using war as the last resort after all negotiations had failed, but he instead outrightly declare war? (He didn't think twice to shoot aya's father in the heart instead of other places meaning he didn't even consider talking at all) I mean if he tried to reason with aya's father and perhaps the dragons, it might come out differently and he don't have to kill aya's father. Even if the talks breaks down and he had no choice but to kill aya's father, he might have not regret it cuz he had tried to solve the conflict peacefuly first......
I mean he did said that in his youth he believed in a flawed sense of justice.... i think he might refer to himself believing in justice of protecting the opressed or the weak or solving conflict or w/e through the use of force alone and not trying to view the problem or conflict from different view and solve it with another means....
Don't get me wrong if someone come trying to harm my family or friend i would immidiately act and if shooting him would protect them i probably would.... i'm just trying to understand yeorin's husband view and regret and how come he saw what he did as "not the best thing to do"
