Then we are back to the original question. If paganism is so bad (according to you), why does God keep putting souls into babies that are going to be grow up as pagans?
But that is not what God taught us when He was here.
Given that we have about 200 different denominations, seems there's some disagreement as what exactly God taught. All scriptures were written by men. Not a single one was written by any divinity.
Your original question is fraught with misconceptions and error. You might as well ask why God grows up little babies to be muggers and rapists and murderers. Couldn't God prevent that? Couldn't God make the world perfect and we would all grow up in 16 children Christian homes with loving moms and dads and eat sugerplums from trees and swim in rivers of bourbon?
Yeah, guess what? God didn't make the world like that. He made us free and that involves challenges and pitfalls. Some people are born into Christian families and have a "head start" and end up rebelling and going to hell. Others grow up as little pagans and find God through a conversion. It's a strange world God made. The consequences of our choices do not disprove the existence of God.
