"Kaido cant die"

[SSJ2]

This is an interesting subject. We know Kaido actively attempts suicide to finally end his life, yet it seems like nothing works. Apparently during execution attempts the weapons fail every time. Kaido seems to be un-killable.. Is it possible he had the immortality procedure done from the Ope Ope no Mi? If so, I dont get why he'd bother trying to commit suicide at all. Also being a fruit user, could he not either drown himself in the ocean or eat another devil fruit to kill himself? None of this makes sense.

Maybe he wanted immortality, but now wants to die. Or maybe (but less likely), he's bored and finds it entertaining to try to die.

As for drowning or eating two fruits, maybe he really wouldn't die or he wants to find another way to die that isn't one of those things, for some reason.
