@HA001 this is for you as well.
I'm going to rip a section from one of my essays, but I think that Kaido specifically wants to die at the hands of the samurai bearing Oden's mantle based on his interaction with the Scabbards:
When the Scabbards first struck Kaido, he sees the visage of Oden:
The scar he recieved from Oden began to throb:
Kaido was astounded and questioned why the Scabbards could pierce him, wondering if they also used Oden's Ryuo:
When the scabbards cut him, he was
insulted that they could hurt him — samurai who did not measure up at all to Oden:
Kaido further tells the Scabbards that in them he saw the visage of Kozuki Oden:
As such, he could have let them kill him (fulfilling Oden's will):
With each throb of his scar he remembers Oden:
He boldly declares that they are not Oden, that never again shall a "monster samurai" of his likes appear:
He laments that they don't even have enough power to open up his old scar, concluding that they cannot do it:
(Here, doing it refers to killing him).
Kaido's affront that Samurai that don't measure up to Oden could hurt him, his acceptance of his death when he saw the shade of Oden behind them, his disappointment that they were far too weak — unable to even open up the scar Oden left — and his final proclamation that the Scabbards could not kill him give me the impression that Kaido specifically wants to die at the hands of the Samurai bearing Oden's mantle.
- He wants to be killed by Oden, and that's why he was so insulted that Samurai that do not measure up to Oden could hurt him
- He wanted to be killed by Oden, and that's why when he saw Oden's shade he could have let them kill him
- He wanted to be killed by Oden, and that's why he was so disappointed that the Scabbards were far too weak
- He wanted to be killed by Oden, and that's why he laments that never again shall a Samurai worthy of bearing Oden's mantle appear before him
If you haven't read it yet, I
strongly recommend the entire essay:
A Look at Inherited Will in the Land of Wano (ZKK: Part 1).
@Garp the Fist: I think his hobby of suicide comes from the emotional scar Oden left on his heart. He wishes Oden had killed him, and began searching for a place to die from then on.
