Re: And when they find them
I strongly disagree.
A prison sentence is a punishment for committing a violation against a society's laws, the idea being the perpetrator being duly punished will gain insight into his/her malversations. It is a way of society saying 'we can not accept this kind of behaviour because it will destabilize our society'. It is why some societies call them 'correctional' punishments, and the places of incarceration 'correctional facilities'. The fact that they don't exactly work is neither here nor there.
An execution is a way for a society to remove elements it deemes unable to be rehabilitated into said society, in other words where the perpetrator is going to be a continued, unrepairable danger to society.
Neither sentence is supposed to be used for a society to 'take revenge' upon a 'criminal element'. The law is never about revenge. It is about rules that can make a society finction.
I find it very hard to believe that people wo have obviously access to global information technology - they seem to be quite effective at spreading malware - do not know or suspect the moral and material implications of sabotaging hospitals or, indeed, any service (think water, electricity) on which a modern society depends to function. I would put it to you they are fully aware of the criticality of the service, as demonstrated by the amount of money they are trying to extort.
I therefor submit it to you that these individuals and organizations, being fully aware of the havoc they are wreaking and their reasons for doing so, are to be considered such a danger to society upon re-entry after a custodial sentence, and are as such are indeed candidates for execution if the laws of the country in which they are deemed culpable of these actions allows for this kind of sentence.
I rest my case.
A sentence - capital or otherwise - is never about a society taking revenge upon a perpetrator.
