The reason why I am overall opposed to PUNISHMENT per se, is precisely because I too have seen too many cases of the most vile acts being "punished" by the legal system, with nothing at all positive resulting.
For one thing, people who do such things are never caused to become valuable members of society, safe to have among us. Punishment only works for people who commit crimes for the sake of personal convenience, from what I've seen. The horrid people we speak of here, respond to the threat of punishment by putting their energy into hiding what they do.
And I am at least of two minds about it. Intellectually, I would have it be so that all such people who have committed anything approaching such crimes, be perhaps branded on their face, so that forever after, it would be known that they must not be trusted. I would have most of them permanently jailed. At the same time, I have had friends murdered, and I know that my emotional reaction is that I would like to carefully drive a bulldozer over the killer's bodies, and then use the machine to shove what remained into a shallow ravine for burial, or perhaps be fed to other creatures which are not a part of our food chain.
But punishment, no. Punishment implies that such a person can be forgiven and redeemed. I don't personally believe that they can be.
Now. If it is one day discovered that people with such proclivities in their physiology can be identified through blood or other tests, and appropriately repaired through chemistry or perhaps brain surgery, I would alter my views accordingly.
In a nutshell, so to speak, these are not acts of a sane person who has made poor choices. They are creatures who are fundamentally too abnormal to have amongst the rest of us.
Yeah,Igor,Brave New World,punish People before they commit a Crime!
Seems work along this line has already taken place 3/4 of a Century ago!
