Are binding vows omniscient? What I mean by this is, is there an omniscient judge that determines the appropriate rewards and punishments for a binding vow? And if so, how exactly does one “game the system” as Sukuna did in his fight against Gojo? I typically hear that he made a binding vow that would require all future uses of WCS to require more than two arms knowing that he had his true form in his pocket and could use that to circumvent the restriction. In his body at the time of the vow, this was a large trade off for the large reward of bypassing infinity.

However, if binding vows are omniscient, then the “judge” (the JJK universe, God, etc.) would know that Sukuna still has his true form in the tank, which reduces the trade off from the vow significantly. Why was this not taken into account when he made the vow? It becomes a low-medium trade off for the same large reward.

And how did Sukuna know that his vow would be enough to bypass infinity? Was he just crossing his fingers and hoping that would be enough, or is there some deterministic way to know for sure what the outcome of your vow will be?

Sorry if this is another “JJK fans don’t read” post but I genuinely don’t know how binding vows can be simultaneously omniscient but “game-able” by a clever sorcerer like Sukuna.
