Do you make any relevant moral distinction between you and a man who repeatedly and consciously kidnaps and slowly tortures to death innocent men and women? Or is one person's falling short the same as another's?
Look, with many there is probably no reasoning about religion, but clearly I do not share your sympathy for BTK. On its face it is abhorent to me, but we'll just have to agree that our value systems are quite different. I like the idea of Hell, and the idea of BTK being cast into its deepest depths.
In terms of salvation, God does not judge on a curve.
You are either saved or lost.
All deserve to be lost.
Now, there may be levels of punishment based on varying factors, but as for being saved or lost it is the simple fact that God views no man as sinless and thus, all men are lost unless they accept the free gift of salvation in Christ Jesus (who was the only sinless man who ever lived)
