Both converted to Christianity, but Klemperer turned back to Judaism after the War. Read Harold Schoenberg's "The Great Conductors" and Norman Lebrecht's "The Maestro Myth" for very illuminating reading. Fascinating stuff.
However one uses "immoralist," I think that Klemperer's Mahler is amoral. It simply lacks the moralizing impulse underneath it. His Bruckner and Wagner are the same. His Der fliegende Holländer is not an extended meditation on the power of love. It is Wagner's score for Der fliegende Holländer. His Mahler isn't a life-and-death struggle of a hero. It is just Mahler.
