Like said in the Wikipedia article, Wisdom Kings are usually represented as wrathful deities(kinda fitting with Kaidō, considering his nature and now-revealed Devil Fruit-ability), as well as protectors of Buddhism(ironic with Kaidō, since he really doesn't protect Wano Country,  but basically abuses it).

At least that's how I see it.
