I could handle immortality as long as other people still died. I think that death is part of what maintains our economy and social system. If everyone were immortal it would serious play havoc on the social structure, economy and governments that exist. Now if I were the only immortal, and others were unaware of the fact, then I would be able to manipulate these systems to attempt to produce the most benefit to the human race. I would undoubtedly fail. All the same, immortality of a single individual, or a rather small number of individuals, should increase the relative value of human life for those immortals. They should become greater humanitarians. The opposite is also entirely possible. Immortality could lead to a higher level of polarization, man would become more good, or more evil. Choices would eventually be mad based on extreme reasoning. Or perhaps apathy would begin to occur, another extreme.
