The writings of Smith might not support it but the scriptures support the view of the unrepentant going to outer darkness. The Telestial can’t be outer darkness either can it?

Therefore, all those who receive the priesthood, receive this oath and covenant of my Father, which he cannot break, neither can it be moved. But whoso breaketh this covenant after he hath received it, and altogether turneth therefrom, shall not have forgiveness of sins in this world nor in the world to come. (D&C 84:40–41)

There is nothing in this revelation about denying the Holy Ghost or having a sure knowledge or having one’s calling and election made sure — just receive the priesthood, and then “altogether” turn from it.

Perhaps there are more people headed for O.D. than is commonly believed.

i clearly recall the time when an Elder Rector Jr. of the First Quorum of the Seventy presided at a mission zone-conference and was asked the question:

What IS the true meaning of …art thou come hither to torment us before the time? as found in Matt. 8:29 (v. 28-33)?

expecting a sunday school answer he proceeded to drop bombs (for three hours!).
‘…the time meant the literal END OF TIME for those who were cast out of heaven… Why does TIME END for those who enter Outer Darkness? Not because this eternal round has no end, it does. But because that is where all matter becomes unorganized…TIME will no longer exist for them because they will cease to exist…the matter and intellegence comprising of their spirit body becomes unorganized…Maybe this dimension is where GOD(S) organizes matter into worlds without number…if this was to be your fate would you not want to possess the physical body any living creature…’
he then went deeper with an intruiging Universalist idealogy (with adequate references).

Forgive everyone…(D & C)

Avoid Final Judgments…(Elder Oaks)

This always curtails me from specific speculation on OD.

So we’ve got the devil (that’s one).

His angels. Well, how many angels does the devil have? If we go by the literal account that a third of the hosts of heaven rebelled against God, that number gets to be HUGE! My own personal guess as to how many children there are of our Heavenly Father is about 100 trillion. That is, those are the other two thirds of the hosts of heaven who followed Christ. So the devil’s angels could add up to 50 trillion.

The sons of perdition. This list is rather small. There are few people on this earth who have known the Holy Ghost and then gone and denied it.

So approximately 50 trillion souls would be in Outer Darkness.
