This novel bases its rehabilitation process as loosing free will. Now although this is an extreme, I believe there are suitable rehabilitation process that will work with time, rather than a quick-fix such as one in A Clockwork Orange. Therapy can be used to help with mental issues, and some minor drugs can be taken to ease the side effects. What they proceeded to do in A Clockwork Orange was a form of torture and brainwashing. Although it "worked" there is much room for speculation due to the loss of ones personal choice. Alex wanted to commit crimes, but he could not...this is not truly a fix. It is the same as keeping him locked up because he became a prisoner of himself.
