In General, many believe that life imprisonment at the expense of taxpayers is not the best option, but it is one of the few humane decisions on the part of the authorities. Every year dissatisfied people are becoming more and may have thought to come up with some other solutions to decrease costs the state to crazy criminals!

As one option is to link to the North or to the tundra, there are hundreds of kilometers of empty space. To survive there is very difficult, no one argues, but it seems to me a much more humane idea than the death penalty. If you arrange the territory, enclose them with the border and arrange something like a desert island, where they can be banished, so you can send criminals there and forget about them without spending huge sums of money on them. To give the opportunity to those who are unhappy with their government, to create their own – albeit small, harsh, but fair, and with such laws as they like. Yes, there will be live Jack the Ripper, the serial killer, but nobody will go and let them decide how to live.
Where and how prisoners will extract resources, food, clothing, with whom – to trade, and generally build their lives to decide only to them. Do you think this punishment is too cruel and inhumane? I don't think so because there are many examples of survival in such conditions.  As a variant example of the first settlers of America, among them were also a few worthy people – mostly criminals, but they wittily in such conditions, organized their society and now as you see rule the world!
