You are reacting as if we are all born innocent when we are not, but are born the children of sin as a fallen bloodline. You apparently have heard nothing of what God/scripture has said or what I have said. If we were all born of heaven we would all go to heaven, but we are not. How is it that you do not understand that we are instead born of sin and our father the devil and ruler of this world?
But no, this world is condemn, even the very elements (which we too are made of) are to be destroyed by fervent heat and with fire; and it is only those who are born out of this world, born of God, born again of the spirit of God who come through the fire.
Thus, there are no innocent children, except those babes of the spirit of God. So, no, this prison world in which we were born and captives of is not the unjust reaction of a just God, but the intentional act of a just God in eradicating sin and evil once and for all. This is mercy. And no, this is not a prison where the innocent children of convicted criminals reside with them and are unjustly subject to their parents sins and penalties--no, but everyone born into this world is condemned already before they are born...because just as we who are saved all become "in Christ" literally as His body, all who are born since Adam are or were "in" him and of him and guilty as his body. In other words, what was unfolded from the one Adam to be many, is now being refolded into the One Jesus Christ..but only includes those who believe that He was sent for our salvation and open the door at His knocking and are born again of the spirit of God, which is the ascension of Christ and us with Him.
Keep reading the scriptures. It will all come clear eventually, but only "precept upon precept, line upon line, and here a little, there a little."
