The earlier interpretation was 10% correct in supposing that none of us can be held accountable for our actions. According to Nietzsche, we can't; at least, not in the sense that current law and morality would have us be accountable. Nietzsche suggests that justice, as we understand it, is an invention of the powerless: they are unable to take their own revenge, to make their own right, and so they invent an abstract ideal of "justice" that will prove them right, in heaven if not on earth. According to Nietzsche, we are not accountable to some higher ideal of justice, but we are accountable to ourselves, and if we are worth our salt, we will be far harsher judges than any higher ideal could be. Thus, in Nietzsche's view, murderers who kill for the sake of money do not transgress any external moral code, but they allow themselves to be controlled by money and thereby show themselves to be weak-willed and shallow.
This summary and commentary should make abundantly clear how difficult Nietzsche interpretation can be. We still find ourselves facing many questions: on what standard would Nietzsche judge a murderer to be weak-willed and shallow? If we are nothing more than wills, what does it mean to be weak-willed? And how might Kauffman interpret Nietzsche's closing remark that we should hope that master morality will return to challenge slave morality if Kauffman so firmly insists that Nietzsche is not a defender of master morality? These are just a few of the questions that remain; the commentary that follows will try to make some headway toward possible answers.
