So the value of the person is entirely in his/her usefulness to the society?
Not entirely. But it certainly trumps a person's "badness" in my opinion.
Well, the problem we are discussing assumes that you do NOT have access to much data (certainly not their rap sheet or the lack thereof) about the frozen people -- their name and whether their contemporaries thought them "good" or "bad" is all you have.
If the civilization reawakening them is capable of calculating an Expected Value for each person based only on their DNA (and other information contained in the body, such as irreversible injuries) which is more accurate than moral differences between the society which froze them and the society which may awaken them, then the moral judgements of the originating society are probably useless.
This month's media thread includes a short article on some people's idea to have Ayn Rand frozen, which ultimately didn't happen. My first reaction was a shudder. I thought, I definitely wouldn't want Ayn Rand preserved forever. My second thought was, What right do I have to say who can and who can't get frozen?
Whatever your thoughts on Ayn Rand, I think this can spark an interesting conversation: What, if anything, should humankind do about people who are widely seen as harmful for the whole? For example, if the Castro dynasty in Cuba or the Kim dynasty in North Korea decide to freeze themselves to ensure they will continue oppressing their countries forever, should that be prevented? (And yes, my opinion of Ayn Rand is such that these examples came to mind.)
