Nihilism leads to terrorism.

from The Rebel by Albert Camus nonfiction ~2 min read

Nihilism, intimately involved with a frustrated religious movement, thus culminates in terrorism. In the universe of total negation, these young disciples try, with bombs, and revolvers and also with the courage with which they walk to the gallows, to escape from contradiction and to create the values they lack. Until their time men died for what they knew, or for what they thought they knew. From their time on, it became the rather more difficult habit to sacrifice oneself for something about which one knew nothing, except that it was necessary to die so that it might exist. Until then, those who had to die put themselves in the hand of God in defiance of the justice of man. But on reading the declarations of the condemned victims of that period, we are amazed to see that all, without exception, entrusted themselves, in defiance of their judges, to the justice of other men who were not yet born. These men of the future remained, in the absence of supreme values, their last recourse. The future is the only transcendental value for men without God. The terrorists no doubt wanted first of all to destroy—to make absolutism totter under the shock of exploding bombs. But by their death, at any rate, they aimed at re-creating a community founded on love and justice, and thus to resume a mission that the Church had betrayed. The terrorists’ real mission is to create a Church from whence will one day spring the new God. But is that all? If their voluntary assumption of guilt and death gave rise to nothing but the promise of a value still to come, the history of the world today would justify us in saying, for the moment at any rate, that they have died in vain and that they never have ceased to be nihilists. A value to come is, moreover, a contradiction in terms, since it can neither explain an action nor furnish a principle of choice as long as it has not been formulated. But the men of 1905, tortured by contradictions, really did give birth, by their very negation and death, to a value that will henceforth be imperative, which they brought to light in the belief that they were only announcing its advent. They ostensibly placed, above themselves and their executioners, that supreme and painful good which we have already found at the origins of rebellion. Let us stop and consider this value, at the moment when the spirit of rebellion encounters, for the last time in our history, the spirit of compassion.
