Keltham does not try to conceal Himself from any Good god's inspection, and it will be immediately obvious to Sarenrae that (though He is truly wounded) He is not a shape that could be changed by that revelation, that everyone else's existence is as intensely real as his own.  Most of His hesitancy about destroying Creation is held within His doubts about whether everyone else here is equally real.  If He were certain that every paving stone in Hell was just as real as himself, that Creation was continually producing new souls and sending thirty percent of them to Evil afterlives and all those people were real, He would be all the more driven to end this.
