Another technical defect is, that a man who has arrived at the degree of degeneracy that Jacques has, ought to have still other vices: as great violence of character, impulsiveness without cause, profound immorality; while, as a matter of fact, except in moments of sexual fury, he appears as a good and honorable man. However, even recognising the force of his bloody sexual monomania, I find that instinctive aversion, characteristic of the good man, to be proper which Jacques feels at the thought of killing some one who is not a young and beautiful woman; for instance, to killing his rival, notwithstanding the favorable circumstances and the suggestions of Séverine. "To kill that man, my God! Had he the right to do it? When a fly troubled him he would crush it with a blow. One day when a cat had got between his legs, he had broken its back with a kick. But to kill this man, his fellow-creature! He must reason with himself, he must prove his right to murder; the right of the strong whom the weak are troublesome to.... But afterwards that appeared to him monstrous, impracticable, impossible. The civilised man revolted in him, the acquired force of education, the slow and indestructible concretion of inherited ideas. His cultivated brain, filled with scruples, repelled murder with horror, as soon as he began to reason about it. Yes, to kill in a case of necessity, in a transport of rage! But to kill voluntarily by design, and from interest, no never, never could he do it!" All that is very true. Where the author has certainly copied after nature is in the personality of Séverine. She is not a true criminal; sensual, depraved though still young, experiencing love only in adultery. Though deceitful, she is nevertheless a good wife and a good housekeeper up to the day where chance had thrown her into evil doing. She is united to her husband, and for that reason she becomes his accomplice in crime, without horror or dread; but afterwards, seized with love for Jacques, she experiences dislike for her husband and wishes to turn the lover into his murderer.
