This reminds me of an awesome movie I saw the other day with Justin Timberlake.
It was called "In Time" (
http://www.imdb.com/title/tt1637688/?ref_=fn_al_tt_1)
I really recommend it!
In a nutshell: the movie takes place in some kind of science-fiction fantasy world where "time" has become the new money. When people hit 25 year of age, they get a "year". A clock starts ticking on their left arm. When you buy something, you pay in seconds, minutes, hours, days,... and when you work, you get paid in the same as well. When the clock hits 0, you die. You are "out of time".
Then the world is divided into "time zones". Where you live depends on how much "time" you have and earn. "Rich" people have thousands, even millions, of years. In the ghetto, nobody has ever more then a couple of days. They are always running and racing against the clock. The movie is about the path of a guy from the ghetto, who through some circumstances, gets his hands on a century.
Really, one of the best movies I've seen these last years (in terms of story and "making you think").
In any case, there was this one line in that movie which reminds me of the bolded part in your quote: "
For one person to be immortal, many have to die".
To which the response then is: "
If even one person has to day...nobody should be immortal".
Sorry if that went a bit off topic, but as it strikes me how similar the bolded parts are to that line of the movie, I felt like I needed to share this
