How about Geum Seong-je character in manhwa, did he became worse villain than now?

WHC2 SPOILERS. if you're asking if he's a worse character in the show than he is in the manhwa, I'd say i think so? I dont remember the ending very clearly, but i remember that wolf made it clear that he was kinda tired of the union, and i dont think he betrayed sieun like he did in the show
