When discussing it with Ten and Aha last night, Blank, this is what I made of how Gremmy died.

Gremmy was passionate about killing Zaraki. Desperate even at this point. And then announced he would become a monster like Zaraki, so as to beat him. The two ideals clashed and resulted in suicide; the only logical conclusion to the paradox. He became that which he was trying to kill. And so he materialized that thought. And the sad fact is. This was the only logical way for Gremmy to lose. Zaraki can't defeat an ability like that through godmode slashes. And that is all he has.

We may not like it, but Kubo had no other logical way to resolve that.
