I believe he loved ''god'' so much, that he had to kill it's modern and twisted perception. Spirituality more than Religion.
Yet it [Nietzche’s “God is Dead”] has, for some ears, the same eerie sound as that ancient cry which came echoing over the sea to mark the end of the nature gods: “Great Pan is dead.” ~Carl Jung, CW 11, Para 145.
