Become Who You Are! ~ Nietzsche Gay Science

This is but one example of Nietzsche‘s wilful contrariness; there is conscious relish in the difficulty that his writings instigate for a reader: I am certainly doing everything I can to be hard to understand myself!

It is tempting to label Nietzsche as an observer of the moral
tradition rather than a creator of a particular brand of moral philosophy, but this risks the implication of passivity and would be entirely ignoring the aggressive vigour in which he systematically and brutally seeks to deconstruct various moral arguments — akin to the pessimistic mole of the sceptic perhaps?

But no, pessimism is not suited to Nietzsche (and nor, incidentally, is scepticism); his argument seems rather to seek a redefinition or a recalibration of moral values, or even just to proclaim encouragement for a consideration of whether our perception of such values can be an accurate one; he does not seem reconciled to the inability of humanity to change and so pessimism or in fact, fatalism, would be inappropriate labels.
