Sorry if this is the wrong forum for this, perhaps it is more of a political/social science issue than philosophical?
I have wondered this for a little while, though. If someone tomorrow came up with a pill that would allow you to live forever, how would prison sentences, and for that matter crime in general change?
Would the threat of a 20 year prison sentence in a sheltered environment carry any weight with you as a penalty if you could live forever?
Would there still be "life sentences"? If you sentence someone to life in prison, and they live forever (they are in a sheltered environment, so there are less chances for accidents, natural disasters, etc.) would this make any sense?
Also, there are those that have been sentenced to 150, 200, etc. years in prison now that are assumed to be there for the rest of their life. How would you feel if someone who has violently murdered people, and been sentenced to say 150 years (which in today's standards would be a life sentence) was released in 150 years to terrorize people again?
What would be better options for punishment? Would the infliction of pain or some other punishment that is today considered inhumane be a better deterent for crimes?
I really do not know, because it seems like it would not be much of a punishment to sentence someone to 20 (30, 40, 50, etc.) years in prison if you could live pretty much as long as you wanted. Also, if someone is a violent criminal that has commited murders, I would not want them back out anytime, but putting them away for "life" which may turn out to be 1000 (1200?, 2000?, 5000?) years would seem kind of a waste of resources to keep them alive.
In any event, I think it is an interesting debate to have.
