Destroyed his confidence + Beat him in his own game + Landed an attack in his own territory + Turned off RCT to charge up CT + Sukuna was forced into hand to hand combat, but Gojo owned him in this fight, hence the reason he took Red right on his face + Sukuna himself was shocked at Gojo's speed.
Gojo now has better feat than tanking 200% hollow purple. We are talking about domain of Sukuna, King of Curses, but it was useless against Gojo.
What was Sukuna's highlight of this chapter?
Smile?
Gojo tanked everything Sukuna threw at him, yet still managed to land a clean attack on his face IN HIS OWN FUCKING DOMAIN!
So yes, Gojo destroyed Sukuna.
Now he need to rely on tricks to win.
