e.g. Assuming not everyone could afford the technology and you have a 30 yro killer who lacks the funds to rejuvinate committing murder on somebody much older. Would that even be a crime or could it be argued that a 2nd class citizen has only tried to revenge or to set right to what they perceive an unjust society.
Playing god is scary. I think we can only do it if we are really thick enough and full of our selves to believe that certain individuals are better than the rest. (... of course all under the usual disguise of democracy and with a system that ensures the majority of those living under it, that what they do is right and for the greater good).
People suck :-/
