If Gregory cared for narrative, Higuruma should've killed Sukuna and final villain should've been Kenny

I was just kinda thinking about the story as of late, just kinda going over characters, and it just hit me like a ton of bricks: hindsight is 2020 and all, but man, it would've been better if Higuruma did it. I mean, narratively, the whole shtick around Yuji was that he had to watch his mentors die for him - Higuruma subverting it and going out of his way to give himself up for the benefit of the youth would've been a great conclusion to that little arc. With Gege doing jack all with unc, it really should've been Kenny and the Merger - Gregory remembered philosophical weight of Sukuna's character only like, what, at the last chapter, lol?
