The whole horror of the much-praised capitalist order lies just in this: Without pity and devoid of all humanity it strides across the corpses of whole peoples to safeguard the brutal right of exploitation, and sacrifices the welfare of millions to the selfish interests of tiny minorities.

Certainly it seems that nature desires to exterminate the human race, as a thing useless to the world, and the destroyer of all created things.

Robots of the world, you are ordered to exterminate the human race. Do not spare the men. Do not spare the women. Preserve only the factories, railroads, machines, mines, and raw materials. Destroy everything else. Then return to work. Work must not cease.

No matter if the enemy has thousands of men, there is fulfillment in simply standing them off and being determined to cut them all down, starting from one end.

Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species - if separate species we be - for its reserve of unguessed horrors could never be borne by mortal brains if loossed upon the world.

Life is a hideous thing, and from the background behind what we know of it peer daemoniacal hints of truth which make it sometimes a thousandfold more hideous. Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species — if separate species we be — for its reserve of unguessed horrors could never be borne by mortal brains if loosed upon the world.

We are all in the same cart, going to execution; how can I hate anyone or wish anyone harm?

It appeared as if the whole world was one elaborate system, opposed to justice and kindness, and set to making cruelty and pain.

As long as man continues to be the ruthless destroyer of lower living beings, he will never know health or peace. For as long as men massacre animals, they will kill each other.

Animals will be seen on the earth who will always be fighting against each other with the greatest loss and frequent deaths on each side. And there will be no end to their malignity; by their strong limbs we shall see a great portion of the trees of the vast forests laid low throughout the universe; and, when they are filled with food the satisfaction of their desires will be to deal death and grief and labour and wars and fury to every living thing; and from their immoderate pride they will desire to rise towards heaven, but the too great weight of their limbs will keep them down. Nothing will remain on earth, or under the earth or in the waters which will not be persecuted, disturbed and spoiled, and those of one country removed into another. And their bodies will become the sepulture and means of transit of all they have killed.

O Earth! why dost thou not open and engulf them in the fissures of thy vast abyss and caverns, and no longer display in the sight of heaven such a cruel and horrible monster?

Some men, under the notion of weeding out prejudice, eradicate virtue, honesty and religion.

To aid and abet in the destruction of a single species or in the extermination of a single tribe is to commit a crime against God, a mortal sin against Mother Nature. Better by far to sacrifice in some degree the interests of mechanical civilization, curtail our gluttonous appetite for things, ever more things, learn to moderate our needs, and most important, and not difficult, learn to control, limit and gradually reduce our human numbers. We humans swarm over the planet like a plague of locusts, multiplying and devouring. There is no justice, sense or decency in this mindless global breeding spree, this obscene anthropoid fecundity, this industrialized mass production of babies and bodies, ever more bodies and babies. The man-centered view of the world in anti-Christian, anti-Buddhist, antinature, antilife, and — antihuman.

We should find ourselves committed to killing a great many people whom we now leave living, and to leave living a great many people whom we at present kill. We should have to get rid of all ideas about capital punishment …
A part of eugenic politics would finally land us in an extensive use of the lethal chamber. A great many people would have to be put out of existence simply because it wastes other people’s time to look after them.

Most of the evil in this world is done by people with good intentions.
