His motives were outrage that had become a habit of mind, the bitterness in his heart, a deep sense of the iniquities he had suffered, the impulse to react, even against the good, the innocent and the just, if there be any. The point of departure and of arrival in all his thinking was his hatred of human law; a hatred that if not arrested in its development by some providential occurrence becomes within a given time hatred of society, then hatred of the human race, then hatred of creation, as is reflected in an ill-defined, constant and brutal desire to inflict harm on no matter whom, on any living creature.

[Il avait pour mobiles l’indignation habituelle, l’amertume de l’âme, le profond sentiment des iniquités subies, la réaction, même contre les bons, les innocents et les justes, s’il y en a. Le point de départ comme le point d’arrivée de toutes ses pensées était la haine de la loi humaine ; cette haine qui, si elle n’est arrêtée dans son développement par quelque incident providentiel, devient, dans un temps donné, la haine de la société, puis la haine du genre humain, puis la haine de la création, et se traduit par un vague et incessant et brutal désir de nuire, n’importe à qui, à un être vivant quelconque.]

(Source (French)). Alternate translations:

He had as motives, habitual indignation, bitterness of soul, a deep sense of injuries suffered, a reaction even against the good, the innocent, and the upright, if any such there are. The beginning as well as the end of all his thoughts was hatred of human law; that hatred which, if it be not checked in its growth by some providential event, becomes, in a certain time, hatred of society, then hatred of the human race, and then hatred of creation, and reveals itself by a vague and incessant desire to injure some living being, it matters not who.
[tr. Wilbour (1862)]

He had for his motives habitual indignation, bitterness of soul, the profound feeling of iniquities endured, and reaction even against the good, the innocent, and the just, if such exist. The starting-point, like the goal, of all his thoughts was hatred of human law; that hatred, which, if it be not arrested in its development by some providential incident, becomes within a given time a hatred of society, then a hatred of the human race, next a hatred of creation, and is expressed by a vague, incessant, and brutal desire to injure some one, no matter whom.
[tr. Wraxall (1862)]

He had for moving causes his habitual wrath, bitterness of soul, a profound sense of indignities suffered, the reaction even against the good, the innocent, and the just, if there are any such. The point of departure, like the point of arrival, for all his thoughts, was hatred of human law; that hatred which, if it be not arrested in its development by some providential incident, becomes, within a given time, the hatred of society, then the hatred of the human race, then the hatred of creation, and which manifests itself by a vague, incessant, and brutal desire to do harm to some living being, no matter whom.
[tr. Hapgood (1887)]

His impulses were governed by resentment, bitterness and a profound sense of injury which might vent itself even upon good and innocent people, if any such came his way. The beginning and the end of all his thought was hatred of human laws: a hatred which, if some providential happening does not arrest its growth, may swell in time into a hatred of all society, all mankind, all created things, becoming a savage and obsessive desire to inflict harm on no matter what or whom.
[tr. Denny (1976)]

As motives, he had habitual indignation, bitterness, a deep sense of injury, a reaction even against the good, the innocent, and the upright, in the unlikely event he encountered them. The beginning and end of all his thoughts was hatred of human law; that hatred which, if not checked in its growth by some providential event, becomes in time a hatred of society, then hatred of the human race, then hatred of creation, revealing itself by a vague, incessant desire to injure some living being, no matter who.
