Perhaps, the problem is with you because if you know just knocking someone down once doesn't mean anything. Then not defeating him in the clash should also doesn't mean much, but you were mocking Zoro for not putting down Kaku in that clash, which directly contradicts what you're trying to lecture me. As far as my argument goes, Zoro overpowering Kaku in the clash should at least mean that he won that clash, and that's a plus for Zori.
