I thought the URL posted beneath this article was an interesting response from the Christian perspective to the question asked: At the outset God made this into a life-and-death situation. God staked the entire future of mankind on this one event. We lost. The moment that Adam and Eve ate that fruit, wheels were set in motion that would ultimately result in the doom of mankind. Without some kind of intervention from God we would all be damned. God does promise to intervene, but it's like building a nuclear bomb and setting it to go off in a large city at 12:00. Then, when all of the people of the city come to you for mercy, you disarm it for them. Does that make you a hero for disarming it or a lunatic for building it in the first place? The whole thing was orchestrated to make us feel dependent upon God. That says a lot about God's character.
In the last couple of days since I read this site, it is hard for me to be glad that Jesus is my Savior, because now it seems like He's saving me from something He started in the first place! A related question that an atheist asked me long ago that I still don't know is: why did God create billions of people that He knew would end up in Hell? Isn't that cruel? Please answer soon if you can, this is bothering me very much.
the christian response is here:
A long read but posted just incase you have time to read it.
