Hello Eric,
Basically, your argument here is that we must concoct a doctrine of reprobation in order to exalt God's place and lower man's place, but that is a non sequitur.
I force my views on no one. I have never said one must believe in reprobation. I simply point out one of many errors in the freewill system. What I have done is ask many many times how the freewill model works, if you place the major points together. So far, no one is telling. If you have a model that works, please share.
(You even admit that we can't know who is elect now, so that is the primary reason to speculate on why people die without believing).
I'm not asking anyone to speculate on WHY one does not believe. We can get to that latter if you want.

I have asked, if God can...and has in the past stepped in so that a man will not sin, or to bring a man in sin back into the fold from a life of sin..then why did God not stop Cain? Why did God not ask Cain to repent? Why did God send Cain away? but I have only asked this one time. Foreknowing and salvation of all men has been the main focus.
This is only negative reasoning on my part. Yet this seems to be something harder to put together then even I thought it would be.
And the idea that us having any choice exalts us is as HP calls it, a paper duck, as if God's glory rests solely on trapping helpless creatures on a path to Hell.
I'm not sure what view you quote here, but it seems to be a mix of ideas. Election is in no way about being just.
God could have done that, and be glorified, and He could have saved everyone and still be glorified, so likewise, he could give us choice and still be glorified as well.
The Gospel is not about how hard God "should be", but rather about how merciful He is.
I'm not asking if God could have. It has been stated that God main goal was to save all mankind. Now we all agree He could have. We all agree He did not.
If this was Gods main goal, and if God forknew Cain would not believe, and if God has shown he can step in a send a fish in order to have Gods will played out, could not God step in a save mankind before Cain was born, being that God foreknew Cain would not believe and being also that this was Gods main goal?
was free will Gods main goal?
or...
was saving ALL of mankind Gods main goal?
You canot have both in this story.
