Not really Gene. Abortion happens before birth. Two live independent
identical individuals can be best approximated by two infant twins.
Killing one of them is most definitely not ok by anyone's stretch of the
imagination, as I've even gotten John to concede that point. Bifurcation
occurs almost instantly after the point of duplication and separation.
Now, if we are dealing with upload copies, that is something entirely
different, but only if the copies are not activated, or if the two
willingly merge back into one to preserve the memory, the experience of
each individual. See Charles Sheffield's _Tomorrow and Tomorrow_.
