About good and evilThese two human valuations refer to things essentially mixed with each other and interdependent. Good causes the evil, and evil causes the good. The dichotomy between a good God and an evil satan is a "dualistic fiction."
In Twilight of the Idols (see the quote above) and later in The Antichristhttp://www.gutenberg.org/files/19322/19322-h/19322-h.htm#THE_ANTICHRIST The Antichrist, 26 & 38 about the moral order of the world. all concepts which explain life as a test or raise an (externally reasonable) moral "task," "purpose" or the "will of God" are considered false. They are a part of the "error of free will" consisting in incomprehension of fatalism of life, i.e. the fact that it is shaped by higher forces.
