Question to Pro life Christians

I was wondering:
If our purpose on earth is to follow God's will and obey and praise him and only he will eventually decide on your fate, then why do you impose anti-abortionism on anyone? Isn't it true that God is the only one who can judge someone? (it says so in the bible if you weren't sure)Since this is true who are you to judge someone and tell them what to do or not to do, isn't it between God and that person anyway and not between God, you, and that person? If you believe it is wrong, fine, no one forces anyone to have an abortion, but for people who believe it is not wrong than let them, they will suffer by the punishment of God anyway right?
As I was told believers in the Christian God have one purpose, to do what he wants and to love and worship him. This is done individually, you are not supposed to impose your views on anyone else, the bible dosen't say that people are supposed to force others to do what they think is right, no, on the contrary God wants every individual to chose for themselves. So do what God wants and let people have the freedom to choose.
