Its just ridiculous. There's nothing frightening to see, except perhaps that some people believe this. That's why no one is watching the video.
I watched the first video, however, because you seem to want someone who is a believer to do so. But there is nothing in what is presented that says that all or even some babies go to hell. Paying for 'Original Sin' as it were, simply means that everyone dies... since the wages of sin is death. Which makes sense, since none of us who came after Adam and Eve were born in the Garden of Eden. We were born outside of that Garden, and outside the reach of the tree of life.
However, life came to us through Christ... and we may now eat of Him, and have life (spiritual). We still aren't in the Garden of Eden though (which I take to mean the spiritual realm), so physically, we all still die. As do babies. And old men. And teenagers. And mothers. etc, etc.
Babies in hell serves no purpose, serves no love, nor mercy, nor justice. Christ never even condemned those who killed him, but instead asked that they be forgiven - for they knew not what they were doing. He had just been tortured, beaten, scorned, and deserted by those who he loved... and all he asks is that they be forgiven. Can you picture this man throwing a baby into a burning hellfire? Since Christ showed us His Father, as His Father truly is, then if you can't see Christ doing it, then you can't see God doing it.
I don't understand how people read these stories, but don't apply what these things say about Him. Instead, they choose to focus on doctrines and men's teachings that are only interpreted from words that could be taken in many different ways. I mean, I do understand... I think it is fear that keeps them from seeing, mostly. But still...
