Once the door is fully opened, everybody rushes through. Once more-or-less targeted assassinations have been normalized by a government, you can be sure that it will be used by every government following them, and ultimately by every other government on the planet. Effective tools will always be used.
Be that mass surveillance, drone strikes, offensive cyber warfare or kidnapping people on foreign soil to fly them to torture camps.
Behind the blind bestiality of the SA, there often lay a deep hatred and resentment against all those who were socially, intellectually, or physically better off than themselves, and who now, as if in fulfillment of their wildest dreams, were in their power. This resentment, which never died out entirely in the camps, strikes us as a last remnant of humanly understandable feeling. The real horror began, however, when the SS took over the administration of the camps. The old spontaneous bestiality gave way to an absolutely cold and systematic destruction of human bodies, calculated to destroy human dignity; death was avoided or postponed indefinitely. The camps were no longer amusement parks for beasts in human form, that is, for men who really belonged in mental institutions and prisons; the reverse became true: they were turned into "drill grounds," on which perfectly normal men were trained to be full-fledged members of the SS."The Origins of Totalitarianism"
Power is not a means, it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish the dictatorship. The object of persecution is persecution. The object of torture is torture. The object of power is power."Nineteen Eighty-Four"
