The darker side of Nietzsche’s ideas was incorporated into the Nazi belief system. Part of the link was straightforward: some things Nietzsche said were pure Nazi doctrine. His comments that ‘The extinction of many types of people is just as desirable as any form of reproduction’ and that ‘the tendency must be towards the rendering extinct of the wretched, the deformed, the degenerate’ could come from any work on racial hygiene. Nietzsche’s central contribution was not these explicitly Social Darwinist views, but his rejection of the Judeo-Christian morality of compassion for the weak. Self-creation required hardness towards oneself: a strong will imposing coherence on conflicting impulses. It also requires hardness on others. Conflicts between the self-creative projects of different people made inevitable the attempt to dominate others. The whole of life was a struggle in which victory went to the brave and to the strong-willed. Noble human qualities, linked with the will to power, were brought out in combat but atrophied in peace. Compassion was weakness, cowardice and self-deception. The Judeo-Christian emphasis on it was poison. In drawing these consequences from his beliefs about the death of God and from Social Darwinism, Nietzsche provided the part of the Nazi belief system which ‘justified’ the cruel steps they took to implement their other beliefs.

~ Jonathan Glover

Loving, of enemies is another dogma of feigned morality, and has besides no meaning. It is incumbent on man, as a moralist, that he does not revenge an injury; and it is equally as good in a political sense, for there is no end to retaliation; each retaliates on the other, and calls it justice: but to love in proportion to the injury, if it could be done, would be to offer a premium for a crime. Besides, the word enemies is too vague and general to be used in a moral maxim, which ought always to be clear and defined, like a proverb. If a man be the enemy of another from mistake and prejudice, as in the case of religious opinions, and sometimes in politics, that man is different to an enemy at heart with a criminal intention; and it is incumbent upon us, and it contributes also to our own tranquillity, that we put the best construction upon a thing that it will bear. But even this erroneous motive in him makes no motive for love on the other part; and to say that we can love voluntarily, and without a motive, is morally and physically impossible.Morality is injured by prescribing to it duties that, in the first place, are impossible to be performed, and if they could be would be productive of evil; or, as before said, be premiums for crime. The maxim of doing as we would be done unto does not include this strange doctrine of loving enemies; for no man expects to be loved himself for his crime or for his enmity.Those who preach this doctrine of loving their enemies, are in general the greatest persecutors, and they act consistently by so doing; for the doctrine is hypocritical, and it is natural that hypocrisy should act the reverse of what it preaches. For my own part, I disown the doctrine, and consider it as a feigned or fabulous morality; yet the man does not exist that can say I have persecuted him, or any man, or any set of men, either in the American Revolution, or in the French Revolution; or that I have, in any case, returned evil for evil.
