Adoption is an option, and you have no idea who that child could become. Steve Jobs was given up for adoption because abortion wasn’t legal at the time.
Additionally, it does not address cases of rape, incest, pregnancies which have a high chance of killing the mother, or children with severe defects (who are likely to remain in foster homes, in the average-to-good case).
You can't define a clump of cells as "good," "evil," or, indeed, as "human." Your own holy book makes no attempt at doing so. If you insist on enforcing your unsupported opinion at gunpoint, it can only happen at the cost of our own free will... just as seen here.
