Wrong. Nietzsche used the genealogical method (as did Foucault afterwards) to undermine the absolutist notion of morality altogether. Moralities built out of an appeal to some Absolute (God, Nature, Science, etc.); the genealogical method displays the inherent subjectivity of these (how they are constructed, how they could’ve been different if conditions were different). Nietzsche doesn’t call them “wrong”, that would be very anti-Nietzschean. Like Spinoza, he argues that ‘good’ and ‘bad, ‘right’ and ‘wrong’ are variable to human psyche and perspectives. Nietzsche deliberatedly deploys the inherent power of ad hominem by pointing to the slavish foundations of Christian morality. It’s mot “wrong” because of some rationalitic argument, it’s wrong cause it comes from a tradition of weakness, and resentment, that praises death and chastises life. Nietzsche’s vitalism isn’t founded on reason, it’s an attitude you’re free to take when you realize the limits of reason to dictate ethics,
