Without a major asspulled plotshield Gojo should have died there:
Gojobros can cope as they want, but durability and RCT shouldn't be enough to take thousands of lethal slashes through the brain per second.
Basic logic: once your brain is sliced from side to side, RCT shouldn't be an option, so let's forget thousands of slices right through the brain.
The one who got asspulled plot helps was Gojo, not Sukuna.
