Same as above; invalid because it already happened in this case. She only had the choice to divorce or to kill the baby herself.
Your acting like one of the two is necessary. She did not have to strangle the baby or to have an abortion. She could have kept the baby or put it up for adoption.
Not to say giving 'someone' a chance at life is a bad thing, but orphans often hate their lives because of piss poor living conditions, and the whole "my parents hated me enough to give me away" thing. Combine that with the fact a proper abortion will terminate a fetus before it is a conscious being, it's a hard call. Abortion robs the fetus of a chance at living, but it does not rob the living of a chance at life.
Right or wrong the undeniable fact is that what she did was horrible compared to any of the alternatives, abortion included. They are in NO way similar, and not even close to being "the same thing."
EDIT: i'd like to note, the first part of my post wasn't justifying killing her baby. I agree she should have given it up for adoption, i'm talking purely from an abortion vs deciding to have the baby and planning to put it in an orphanage.
