[ She means, were the Elders right and Itadori should have been executed. ]

It might not have happened exactly like this. If we were lucky, it might not have happened for some time, but it still would have happened.

[ Practically speaking, without concerns for morals, the best course of action would have been for Itadori to consume at least half of Sukuna's fingers and kill him. Then, Sukuna could only ever get half as strong, and the odds were in jujutsu society's favor that whoever had to deal with that could do so.

It doesn't matter, however, because they took the chance they did. There's no do over for something like Sukuna, and no other situation compares. ]
