@ConquistadoR was right the entire time, Kaidou really is Doflamingo 2.0
Kaidou getting tossed around by Base Luffy and acknowledging him as his equal, will age the same as Doflamingo getting tossed around by Boundman when later even Cracker was smiling in its face.
I will be defending Kaidou in a few years time when they are calling him a low top tier/inbetweener.
