In a thousand years who will care? If Bible banging Christians are correct it will be those cast into the ovens of hell - right after their demi-god Jesus returns at the head of a heavenly calvary charge with angels all riding white lipizzaners riding down to clobber non believers and believers who don't quite believe enough. But this punishment will not realy come because of abortting babies - because really it comes for the sin of not having accepted Jesus Christ (that doppelganger of Mithra) as their personal Lord and Savior. I should know cause I used to be a preacher long ago - before I saw the light - BABY!
Other than such arguments as this, this question (of abortting) will depend on opinions or other non-Christian religious myths and doctrines. But since I know that the odds of mankind saving the biosphere from its destruction from the hands of civilization is about nill, I say: let's wait a thousand years and ask earth to see if anyone cares:
Nope, no one there seems to care.
