Fuck oda.
If he can keep kinemon alive through all the fucking bullshit plot armor just so he could let him meet his wife who has been waiting for him for 20 years, he should have kept ashura doji alive too to see a free wano.
The rest of the scabbards except kawamatsu didn't have to live the last 20 years seeing wano turn to a hell hole.
And ashura contributed a big portion of the warriors too.
If he was gonna die anyway, he should have died at the hands of kaido, while fighting bravely.
That way, kaido gets a much needed kill, and ashura can die honorably in battle.
But noooo..
He shall die to some explosive, when fucking pell survived a bigger one with not even fucking basic haki.
Fuck wano.
