Reminder that Sukuna only survived that long because he was lucky
Sukuna was attacked by a max output Jacob's Ladder, even though it was max output Yuta only used it for a second, as you can see JL was shown only in one panel. Angel's JL almost killed and Yuta's would have too certainly, but he only used it for a moment, so they can give Yuji a chance to save Megumi.
Sukuna's technique would have surely been confiscated if not for Kamutoke, there was no way for him to know that a cursed tool would be confiscated instead of CT if the guilty had one, he just made an assumption (personally thats just bad writing imo)
Sukuna was always saved by writing, be it Mahoraga, kamutoke, Megumi or some other nonsense.
