Kaido just says he believes pirates do this. There is no statement saying he thinks he's an exception.
Show a specific part of this statement that implies that Kaido thinks he's am exception to his own definition of pirates
Lol, it was just a generalized statement he made to the scabbards who know almost next to nothing about the World of piracy. He wasn't saying ALL pirates do this, but telling them that they don't know what they are getting into by putting their fate into the hands of pirates. It was mind games, and they didn't buy it for a second, because they believe Luffy is going to be the one to bring the Dawn to the World, and that he is different.
Again, Kaido is the man who went SOLO to challenge the other Yonkos and the Marines, because he was searching for a place to die. Him running from Luffy because he gets beaten so badly makes absolutely no sense in the confines of the narrative of his character.
