And to me bounty is actually justified. in the eyes of cp0 agent he saw those three working together against yonkou and later on kidd and law takes on bigmam whereas kaido takes on luffy beats him twice and kill him too, beat yamato, and gets damaged by momo bite and gear 5 awakening which lead to luffy victory, basically luffy just screwed everything out from him to beat kaido and luffy didn't woke up for 7 days where's law and kidd didn't go out in the first place , and were stationed at harbour since 7 days barely have any injuries at the same time. i would say equal bounty is very justified, and kaido already said haki tops it all in the end no matter how strong the devil fruit.
