Free will is just an empty metaphor inside this realm. The sexual revolution unleashed a potent rebellious impulse that contradicted the anxiousness of freedom-less reality. For Lawrence, sexuality was primarily a moral issue. Those that denied and suppressed their sexuality subverted the hope of people coexisting peacefully and happily. What Lawrence did comprehend is the polarity inherent in love between human beings, specifically between men and women.
Lovers can also be betrayers.
The line between love and hate is thin indeed and the ubiquitous loneliness of our post-modern culture thins the line further. Nevertheless, it is still necessary to demarcate the line, transcribe its limits. Our only defense against fate is passion, unruly and free, but committed to humanity. Lawrence's attitude toward women, much like Henry Miller after him, seems problematic. He was, from start to finish, dominated by women.
