We already have. We have lost great leaders, teachers, mothers, fathers, grandchildren, etc... Not all of the abortions are killing criminals like Freakonomics stupidly claims.
I know this has been my strongest argument on abortion since I was a teen....evenbefore I became a Christian. Sometime, somewhere...someone mentioned it to me at an early age and I never forgot it. I drilled it into my kids/grandkids that humans may screw up but God doesn't make junk. Everyone a has purpose in this life.
