Actually, Pedro is fine with dying on WCI - he just didn't want to die during his battle with Tamago, before the Straw Hats had accomplished their goals. He just wanted to know that the dawn of the world had arrived, not to see them ushering in the new era. So him sacrificing himself at the end would make sense, though I'm not particularly adamant one way or another
