Je me suis armé contre la justice.
Je me suis enfui. Ô sorcières, ô misère, ô haine, c’est à vous que mon trésor a été confié !
Je parvins à faire s’évanouir dans mon esprit toute l’espérance humaine. Sur toute joie pour l’étrangler j’ai fait le bond sourd de la bête féroce.
J’ai appelé les bourreaux pour, en périssant, mordre la crosse de leurs fusils. J’ai appelé les fléaux, pour m’étouffer avec le sable, le sang. Le malheur a été mon dieu. Je me suis allongé dans la boue. Je me suis séché à l’air du crime. Et j’ai joué de bons tours à la folie."""
