fetus is not alive therefor no life is ended.and who cares if its "the potential to have one". anybody could have the potential to be anything.i could have the potential to be a serial rapist, but im not going to.
i'd definitely say let her get the abortion. unless you are over 20 or not in school it's a bad idea to raise a child by yourself. unless you really really want that baby. then, you keep that baby. you go ahead and keep it.
