See RFC 3675 for a discussion of some problems with something

Of course, one could also examine RFC 3514 for some ideas as to
how to implement such ideas. :-(.
As others have said from different perspectives, if one can
clearly differentiate between Good and Evil or Clean and Unclean
and get universal agreement about the boundaries, then many
things become feasible. Unfortunately, the quest for such
boundaries, and debates about them, are, depending on which
sources you believe, eight to 12 millennia or more old. Perhaps
it will be resolved in the next few years, but that would be
truly surprising.
