On the one hand,culturaly the death of God seems to have liberated a self contained individual (perhaps the legacy of monotheism) from guilt. Getting beyond disillusionment the guiltless, while existing , seek and find a more authentic spiritual experience with what is and they feel compassion . They do not imitate , they simply are transformed.
In this way the Death of God is an assault on man's ego and the idea, traveling through culture to the individual ( the mind set of monotheism), is a step toward liberation. An enlightened culture is at last possible and we see "Spiritual " movements on the rise.
On the other hand, the idea, traveling through culture has assisted the growth of "Consumerism" and the "self-contained individual" who once looked to God now looks to Consumer Culture for absolution. In that sense there is a new "self-contained individual", less sensitive and very materialistic. He has been liberated into the arms of Corporations.
I don't know how else to answer the questions . You have equated the issue of "Gods cultural death" to one's awakening to that issue through the JW experience. While that may have some validity, the cultural effect of God's death operates within all organized religions (including JW) regardless of dogma. Coming out of JW merely allowed more expression of some of those effects.
