I think that the important thing is to be aware of the realm we are talking about. What is true in the material (body/mind) world isn’t necessarily true in the spiritual (soul) world. Nietzsche was probably the greatest mind modernity has produced, but apparently he died too young to develop his soul to a decent level. In the mind-body world, which is also the animal world, power is indeed the main thing. Here the end justifies the means and everything is permitted. But for those who strive to be more than an animal there is another layer of reality where power isn't only not the goal, but indeed something to avoid at all costs because it is the most potent corrupting force that exists.
