Quote #40
"Strumpet!" The Savage had rushed at her like a madman. "Fitchew!" Like a madman, he was slashing at her with his whip of small cords. (18.92)
Exactly.
Quote #41
Drawn by the fascination of the horror of pain and, from within, impelled by that habit of cooperation, that desire for unanimity and atonement, which their conditioning had so ineradicably implanted in them, they began to mime the frenzy of his gestures, striking at one another as the Savage struck at his own rebellious flesh, or at that plump incarnation of turpitude writhing in the heather at his feet.
"Kill it, kill it, kill it…" The Savage went on shouting.
Then suddenly somebody started singing "Orgy-porgy" and, in a moment, they had all caught up the refrain and, singing, had begun to dance. Orgy-porgy, round and round and round, beating one another in six-eight time. Orgy-porgy… (18.98-100)
Notice that John says to kill "it," not "her." Huxley himself calls Lenina "that plump incarnation of turpitude." While John is beating her up, he's really trying to beat up all the dirtiness and promiscuity of the new world.
Quote #42
It was after midnight when the last of the helicopters took its flight. Stupefied by soma, and exhausted by a long-drawn frenzy of sensuality, the Savage lay sleeping in the heather. The sun was already high when he awoke. He lay for a moment, blinking in owlish incomprehension at the light; then suddenly remembered— everything.
"Oh, my God, my God!" He covered his eyes with his hand. (18.101-2)
The little dash before "everything" leads us to believe that John did after all have sex with Lenina. It's possible he's just remembering the flogging, but as we said, in a book where sex and violence are so closely tied together, it's unlikely that the climax of violence could occur without the climax of sex. Also, it was an orgy—everyone else was doing it. And the line about him covering his eyes is important (think famous Greek tragedies). Read John's "Character Analysis" for more.
