Now, here is a hypothetical scenario I came up with. At the moment, there are times when someone is put away for a life sentence. This usually refers to how long they will live naturally. Then there are extreme cases where they get multiple life sentences. It was at these cases of extreme life sentences that I started wandering, how would they even define a life sentence in this case should the individual life past a certain age? Then it brought up, what if we were talking about someone who is immortal? Obviously even giving them one life sentence would be odd since their natural life time is, well, forever. You would have some moral situations to go over when it comes to being a just and unjust sentence. On one end, life sentence means as long as they will life. On another, someone who is immortal cannot die. It could be easily argued that their time doesn't fit the crime.
So, how do you suppose a life sentence would be handled for someone who was immortal? Remember, just a hypothetical situation.
Just a note: Please do not turn this into any form of political debate concerning weather or not life sentences are justified when in question about normal situations. This is for a completely fictional situation involving someone who is immortal and how a life sentence would be handled.
