If she started a new life because she was stupid, that's just too bad, if she doesn't want the baby after it's born, there are millions of people who will adopt it, but women should learn abstinence and respect their bodies.
there are public responsibilities with this though.
statistically, "unwanted pregnancies" occur most often among lower class citizens, often times outright poor citizens. this immediately puts a large burden on the tax payer because unwanted children growing up in a low income family = criminals. whether the women deserve some sort of "punishment" for being irresponsible, well, that's another discussion, but in the interest of the entire country, and you're wallet, when a poor 16 year old girl from Rinky Dink Zdroj gets pregnant and wants an abortion because she knows that she doesn't have the means to raise the child, on paper, an abortion would be in the best interest of the state.
now, i'm not going to argue with someone about how it's so immoral to think of a child only from a financial perspective....but if a 16 year old girl raises some kid in squallor and he ends up stealing and cheating because of his circumstances growing up....the only thing you, as a citizen of this country, are concerned about is your personal safety and how much it's going to cost you because he's a criminal.
