I've definitely hated him to the guts, but dang I love a morally grey character!! He's always been despicable in the ways he handled his feelings towards FL, but when it comes to him ruling, he was shown to be benevolent and caring towards his people. He was greedy and selfish and trusted the wrong people for his selfish desires, but ultimately, his character really was admirable. Unlike MRW who could only go insane with another's sacrifice and never truly redeemed herself, SuYu proved that his heart was in the right place, that he is someone worthy of pity and admiration. Honestly that last episode did break my heart, but it was the only right ending for him
