Those are concepts that wholly absent from the early christian writings, including the gospels.Your philosophical speculation is as good as anyone else's.
The Catholic faith it's not based only in early Christian writings.
And it doesn't meet the challenge anyway: Since you claim that god creates every soul at the moment of conception, then the destiny of each soul rests under his wing.
No. Every soul has free-will.
Including abandoning such soul to a supposed hell of nihlism.
It's a personal free choice. The first requirement is to accept the existence of God. This requires the same faith applied to the axioms of the scientific method. Is it that hard?
Again, why would a god of love and justice do that? After all, that soul didn't ask god to come to existence.
This is a ridiculous teenager whining. The human nature is designed to pursue perfection (you need to exist to do that). You need a great amount of will to fight against this default feature of human nature.
