Troll leave now..
Serious question for you doc: let's assume this story was true and factual, what method of punishment would you recommend? With individuals of this mental state a hefty fine (a previous suggestion of yours) is worthless?
It's unlikely these people could be rehabilitated successfully, if this was a drug induced state and they could be reintroduced to society, should they be/do they deserve another chance, would they be accepted by their communities?
Is life in prison a legitimate choice? Why keep these people alive any longer, putting others at risk (correction officers and other non criminals that they'd be in contact with) and I won't even touch on the monetary drain they'd be.
In this case are you against a death sentence? I'm not (I'm not saying I'm right rather just sharing my opinion) or drop them off in a war zone area and let them fend for their selves.
I'm looking forward to your reply.
