Hickman REITERATED once again that T'challa will kill Namor when he is done with him.
That had to be for a reason.
I dont think THIS is what the reason was though. I think it will come later down the line.
I really, really could see Namor "saving the day" in the end while working for the Cabal. Like, Namor turning on Thanos and Co. at the very end when they are about to do something that goes beyond killing an Earth. That will be his "purpose" and that will kind of redeem him...
before T'challa then kills him. I 100% think T'challa is going ot do it now. No reason for Hickman to keep bringing it back up.
Could Alt reality Thanos be the Great Destroyer?
