Okay..here we go
First off most women (I know this because I asked my ObGyn) do not discover that they are pregnant until they are around 4 weeks pregnant. Add it up, that is more than 28 days (I've also read that the heart starts to beat as eary as 21 days, that's a mere three weeks).
So you are saying that it is all about the soul?
When do you believe the soul becomes a part of the body?
Is there some magical moment in which the developing human automatically has a soul?
If you want to use the Bible:
Jeremiah 1:5 "Before I formed you in the womb I knew you,
before you were born I set you apart;
Psalm 139
13 For you created my inmost being;
you knit me together in my mother's womb.
Oh as far as thinking goes.
Do you know how hospitals determine that a patiend is clinically dead?
They measure brain waves and brain activity.
As early as 6 weeks brain waves can be measured.
Tell me that child doesn't deserve a chance.
And you mention the child not being wanted or not being cared for.
I say fuck that!
I have 4 younger siblings.
All of them unwanted by their biological mother.
All of them spent years in the system, in and out of foster homes, living on the streets.
Their first few years were shitty.
But then my family found them and adopted them.
Ask them now if they think they should have just been aborted.
Sure, there life was hell to begin with, but that doesn't mean they didn't deserve a chance at life.
