A lot of people that have children are not fit to be parents. If I'm not taking care of that child, I cannot judge the mother's decision on whether she decides to go through with the pregnancy or not.
I can however speak to a lot of unfit individuals bringing life into this world and many do not nurture, teach, discipline, or guide those lives in the right direction.
The consequences of irresponsibility can be ignored and the parent or parents can try to make a better life for the child or they can continue to be irresponsible and eventually raise an irresponsible child into an adult. Most of the time it's the latter.
That same child now an adult with poor discipline and little education is typically not going to develop into your model citizen.
People want to pick and choose what they have all this morality about like premarital sex, birth control, and Plan B pills don't essentially terminate life and are very much immoral and unnatural.
The woman with the abortion might be smarter than the woman with multiple children by multiple men and living in poverty depending on who you ask.
