I would prefer we create policy which gives people the greatest freedom to make intelligent decisions. See, nobody that gets laid has my outlook on the value of life. If culture hasn't taught them to value life, and enjoy the prospect of raising children, and having a family, then the maternal(or paternal) instinct to have children, and protect their young will have an effect on their decision. There is a lot going for fetuses.
Nobody is out there getting pregnant just to have the evil satisfaction of destroying life with an abortion, also considering they are at a certain risk of death during it.
And perhaps there are a lot of people who are getting pregnant, and then realize they cannot support the child, and wanting to have an abortion. And perhaps they are being irresponsible, but it would be irresponsible of us to not provide her the ability to, because if we force her to have a child she cannot support, we will have likely created a child who will live in poverty, with less than stellar parents. Maybe you would like to make the mother pay for her irresponsibility, but I do not want to make an innocent bystander(the child) suffer because of her stupidity.
