Maybe God's way of trying to stop it is to enlist mere mortals to stop it.
Or perhaps the ones for abortion are the ones following the God's will. That's what I was trying to hint there..
There's no telling of who's really following the ways of God in this matter, simply claiming to be the one for God is not the same as true.
God gave man free will...what man does with that free will is up to him, but he will be held accountable for it by God.
In their narrowmindness the jews executed Jesus and are still waiting for a jesus. All this was done in the name of God by mere mortals who believed they were enlisted by God to rid this person who they believed was a blasphemer. Apparently they were wrong and are still waiting in denial of the past.
The catholic church was in wrong as well for centuries in their personal greed, yet they were claiming to be the holiest men on earth following God's will. Be careful, if you want to be a zelous follower of God, because defending your own personal belief with God's name can be a sin.
You shall not make wrongful use of the name of your God
