in the end the character development felt totally incomplete, and the open ending left much to be desired. The author's hesitancy in this situation from ch236 till the very end resulted in numerous possibilities like A LOT!! Considering the nature of Jujutsu Kaisen, Gojo's survival isn't entirely improbable and that's what makes everything wors. Like you can argue about how he's gone but also do the same about the reasons why he could he alive! Overall such disappointment it was! What he did with Gojo ruined the whole story.
