I am not arguing that we shouldn't try to find out why people do what they do and try to fix it before harm is done. I am arguing that once you step over the line, I don't care anymore.
In my sick little world of absolute personal responsibility, your life is your own. You do with it what you like, when you like how you like. When what you do hurts somebody else, you have stepped out of the arms of liberty and into the crotch of licentiousness.
I believe that there are very few "normal" people out there. I believe that "normal" isn't the norm. We all have our problems. I have a high propensity to seek physical gratification from substances. I am highly addicted to nicotene. I enjoy alcohol so much that I must restrain myself more than most from partaking of it. I don't see other people who have a lot of the same cravings I do.
A molester or a rapist is a person with a different set of cravings. Just as I cannot help myself with my cravings for tobacco and beer, I believe that they cannot help themselves when it comes to desiring a child to do adult things with, or in the case of outright rape, degrading and punishing women (or children) as a means to feel powerful.
That being said, when my wife asked that I refrain from drinking, I refrained. If nicotene (I use Coppenhagen so as to not cause other people health problems), causes physical harm to others, I would stop that too.
I believe that some crimes should be viewed as illnesses. It just so happens that sex crimes tend to be incurable illnesses, and hence society is best served by life sentences or the death penalty. I do not see our prisons as rehabilitation clinics so much as they should be retribution for crimes. Prisons rarely rehabilitate, hence my views are the only people who should be there are those who commit crimes against life, liberty or property as punishment for those crimes.
If a person has a lust for children, I have little doubt that they know that it is wrong. It is their responsibility to seek treatment BEFORE they act on their lust. After they act on it, it is my duty as a juror to convict and hopefully to sentence them to a life of "rehabilitation" in one of our fine facilities.
