On the subject of Garlemald, correct me if I'm wrong but outside of Cid, hasn't our main interaction with Garlemald been with it's military? Judging a country solely on the actions of their military seems skewed to say the least.

On Arenvald, having him become a sacrifice in Fordola redemption arc would fit kinda well, which sucks because I definately prefer Arenvald over Fordola.
