Kizaru is a good guy
Kizaru is secretly a good guy, probably working with Dragon I believe this is true for many reasons:
He always completes his missions to the exact letter, he has no interest in taking care of the straw hats or pirates even when opportunity presents itself so easily on Egghead, always doing the absolute bare minimum to seem like he’s cooperating yet not an overachiever to get too much attention or recognition
He is always just barely too slow or barley too weak, Zoro and the gang getting away from Sabaody and all the pirates he fought there, Luffy on Egghead, Marco on Marinford, Sentomaru, etc. he is always letting people get away, or his battles just happen to be moot, he just happens to choose Marco who is a well known pirate with his devil fruit? He lets Rayleigh block his kick when we know he should be able to execute Zoro in that moment, he fights Sentomaru when he knows that means Vegapunk could get away, the only time I think he tried a little bit was when he got yeeted by Luffy and sped back into the battle and made the clones so he could influence the scene more, Marineford he could of killed Luffy or ace instead of destroying the key and only inconveniencing them slightly, etc.
The whole thing on Egghead with him feeding Luffy and how he listened to that call and information about the elders descent is a massive red flag
He seems to have hidden motivations, and while contributing to “justice” his presence feels purposefully nerfed, I really think dude has alternative motives
