People tend to misunderstand Nietzsche’s “God is dead” comment by taking it at face value, but his warning was a bit more pointed — famously warning that once Christianity lost cultural authority, Europe would become irrational and inhumane — it would become morally unmoored. Without transcendent standards, moral language survives but becomes raw power dressed up as compassion. He predicted the rise of what he called slave morality: resentment reframed as justice.
