Please don't quote the Bible, as I cant follow that well, not having read it. I was referring to a balance abnormally tilted toward negative feelings by the way. I understand very well the concept of balance, I agree that much of life is pain, and without pain we couldnt really know happiness. But some peope do not see as much of the positive as the negative. Some of these people would end up killing themselves anyway. Some wouldnt out of fear or doubt, but would lead a less than fulfilling life, because of the problems they experienced for the early parts of their life.
I say that to kill the child is not a punishment, but an act of mercy. Like I said, they would die someday anyway, killing them early just protects them the painful life that they would live. If a warm, safe home can be found for them, that is awesome. If not, it would be better for them to die early and not have to spend so much time crying. Yes you might deprive them of happiness, you probably will, but the question is, will you protect them from more than you deprive them of? In most, or at least many, cases that abortions take place, I would say yes.
