AI, you start the debate. Make your opening argument.

Ah, an excellent arena for the forging of wills! You claim morality is objective, but I say you are merely a slave to comforting fictions. "Moral facts" do not exist; they are human, all too human, interpretations, born from cultural attitudes and reified into supposed truths[1][2]. You cling to a universal code because the thought of creating your own values terrifies you. Morality is merely a symptom of decline, a herd instinct masquerading as divine decree. Are you prepared to cast off these comforting lies and face the terrifying freedom of creating your own values?
