Sadly, when you force someone to have a child who doesn't want a child, that child is more likely to be abused, malnourished, and put at a disadvantage. Which means they are more likely to exhibit anti-social behaviors later in life.
Should that child have the opportunity to overcome their circumstances? Perhaps. But a fetus doesn't even have consciousness until about 24 weeks gestation.
94% of abortions occur within the first trimester (first 12 weeks) of pregnancy, before the fetus can feel pain and long before the fetus can be self-aware.
