Kaidou wants to make them subordinates? I thought he was really hell-bent on killing them, thoughβ¦
I think that's consistent with his behavior and personality so far. He was drunk when he said he wanted to kill them so he probably doesn't remember that he said that or if even he did, he's shown to be an impulsive person in all his appearances up to now like his decision to jump off Sky Island or wanting to attack Whitebeard for example. I think that's what makes the Wano arc very interesting, all the events are very unexpected because of Kaido's erratic moods and spontaneous actions like his sudden early appearance in the arc which lead to an even more surprising early encounter with Luffy.
