I've long contended that capital punishment does society a disservice. It appeals to the very instincts that should not be involved in decisions of that magnitude.
Popular arguments in favor of the death penalty include:
Cost to the taxpayer. This is a bogus argument but I'll address this.
Deterrent factor. This is hard to argue, the degree to which it is a deterrent isn't quantifyable and to make it a better detterent it should be employed more readily. I say there are many ways to deter crime, some are not worth pursuing.
Removing the monsters from society. This is what my idea deals with.
My idea consists of penal colonies which is not a new idea. I just wish to add new twists to them. Before I continue I must state that I do not argue this from a practical standpoint. I wish to debate this in theory, I know that the Aussies are not going to give me their land for this idea.
Ok, we'd need 2 islands. The islands would exclusivly house criminals who have been deemed unfit to take part in society.
Why 2 islands? Because the pridian flaw of penal colonies was reproduction, it's unfair to the scions and eventually the colony becomes a first world country (Japan, Australia).
T.H. White in
this book suggested the same thing (I read the book AFTER I had this idea, deb can back me up on this). In his version children were removed from the island.
So, if we have a person who is unfit for society by all means he can be outcast. He can work the land to survive and fend for himself in the wild. No cruelty needs to be performed by the remaning members of society (e.g. you space them out, let them find each other if they wish but their companionship isn't intentionally used as punishment).
I have more to say on this but would like to pause for your input.
