The central message of this book seems to be that the freedom to choose (good or evil) is fundamental to mankind. Indeed, this element of moral choice distinguishes humans from machines and robots. However, is moral depravity better than forced morality? Are evil and suffering (freely chosen and caused by people) better than a docile, peaceful state (engineered by the Government)? People like Alex, the prison chaplain, and F. Alexander and co. seem to think so. The State is more interested in stability than any debate on morality and ethics, however.
Behavior that is not chosen, but dictated or forced, is neither moral nor immoral, because the freedom to choose one's actions underlies the very concept of "morality."
Alex is the ultimate poster-child for amorality, since he delights in violence for violence's sake.
