Aha i get it. So Hak orders mundok and the wind tribe to except Soo wans reign, not fight back and make peace to keep the tribe safe. Orders the wind tribe in the xing arc to not fight back or use any form of violence no matter what the Xing soldiers do. Helps the fire tribe in the Tully arc despite what they did to the wind tribe. Orders the soldiers not to hurt innocent civilians during the war. Keeps his  composure and puts his loved ones before himself when coming to the castle despite being treated like garbage. actually and genuinely still cares for Soo wan despite his betrayal that forced him to leave his name, family and home to live like a fugitive and hurt one of the dearest people to his heart. 
While in the other hand so far Soo wan chose to kill king Il instead of finding a better way, the Genius that he is. Chooses war in the Xing arc without even considering talking it out first. Not to mention being ok with what his father did with the excuse “this kinda thing happens in war”. Allows the advisor to threaten yona and the dragons with hunting them down not to mention other bullshit he allows him to do. Chooses to kill Mei without any kind of hesitation.
And in the end it turn out that Haks only language is violence. Hak only knows how to act with rage. Hak has no control over his feeling, specially his anger. And has no development what so ever... 🤔🤔 aha makes allot of sense.
#make it make sense.
