Unless of course, Moria's zombie army is something less than legal...Then again, that's not good enough of a reason to kick off a powerful ally from your ranks.
THE POINT: I don’t think he’d be officially kicked out.
But I have a sneaking suspicion that Kuma might come out and kill him/destroy him for not fulfilling “his duty.” I dunno why I’m assuming this, but I’m just waiting for Bartholomew Kuma to flip out and do something like this. Seems plausible.
