I see your point. People are quick to persecute Hee ryang for those murders but it's so obvious that he has no choice between killing and saving them. He's a soldier that obeys an higher authority. If he had said no to killing them? Someone else would do it,and after that? It's his neck on the line for being a traitor. If Hee ryang was the king or a crown prince then the fault is solely his.
Yeonjo should first direct his anger to the prince turned king that gives hee ryang orders.
Take for example his becoming a governor in that town to get rid of the hojoks,it was clearly a dirty job and he didn't particularly want it but did he say No? Of course not,cause he can't.
If they switched places and yeonjoo got the order on hee ryang's he would have gone through it with no remorse also. Frankly speaking,hee ryang has no reason to put his life or career on the line for yeonjo's family,especially for someone who's family didn't actually care for due to being a concubines son
