Again I said that Whatever he’s doing is for his agenda… For whatever reason he is supporting Teach’s plan to become a king… He was the one advising teacher about Koby being part of Sword and therefore not being a good enough hostage to blackmail the WG… He seemingly captured Garp so that Teach could have a good hostage to carry out his plan
So yes, some part of Teach’s plan fits whatever it is Kuzan wants… so Kuzan does whatever to ensure Teach’s plan occurs… But the point remains, Kuzan is specifically helping Teach because it fits whatever he already wants… Kuzan isn’t sacrificing anything here… he already wants this to happen for some reason
Therefore the question is, what happens when what Kuzan wants is no longer in line with what Teach wants… Maybe you think this will never happen, that somehow everything Teach wants will be exactly what Kuzan wants… I doubt it
