I haven't made any conclusions, and I think you err when you state that thes same Saints who spoke of the freeness of the saved also rejoiced thankfully. In some cases we really don't know much of anything else that these early Saints said.
I am in fact pretty certain that I not err with regards to the fact that many saints both rejoiced thankfully and spoke of human freedom and the dangerous risk of damnation.
I obviously I haven't read all the writings of every saint, but I do know for a fact that several saints wrote both about the narrow path of salvation and yet still thanked God for it. St John Chrysostom is probably the best example, being known for both his rather harsh sermons warning his Antiochene congregation that fewer than a hundred souls in the city would be saved, as well as for writing some of the greatest hymns of praise and thanks to God known in the Eastern Church. And St John Chrysostom is not the only big name to have written such things: St Basil, St Gregory the Great, St. Augustine, St John Climacus and many others all shared similar sentiments.
If you have counter examples then I would love to hear them, but as far as I know there are very few, if any, saints who did not rejoice thankfully in the Lord. And while there were some who held to the hope of universal reconciliation, the majority of these same saints also held to the reality of an eternal hell.
In any case, regardless of individual saints the fact remains that both free will and the necessity of joy and thanks in the Christian life has always been a central and non-negotiable teaching in Christ's Church. These doctrines are found throughout scripture, in the writings of the Fathers and indeed in the liturgy itself- we cannot sidestep them and still claim to be walking in the footsteps of the saints now in heaven.
Again, I haven't drawn any conclusions, but it sure is tempting to draw conclusions about people who would call a God who sentences most to eternal torture all-loving.
This is only tempting if one does not believe in free will, and therefore blame God for "sentencing" people to hell rather than realizing that they have damned themselves there by their own choice. This is of course what this entire thread is about, and I will leave the philosophical debates to those more knowledgeable than me, however I will point out that scripture is
absolutely clear that we cannot lay the blame on God for people doing evil and going to hell.
Sirach 15 11-20
Do not say, “It was the Lord’s doing that I fell away”;
for he does not do what he hates.
Do not say, “It was he who led me astray”;
for he has no need of the sinful.
The Lord hates all abominations;
such things are not loved by those who fear him.
It was he who created humankind in the beginning,
and he left them in the power of their own free choice.
If you choose, you can keep the commandments,
and to act faithfully is a matter of your own choice.
He has placed before you fire and water;
stretch out your hand for whichever you choose.
Before each person are life and death,
and whichever one chooses will be given.
For great is the wisdom of the Lord;
he is mighty in power and sees everything;
his eyes are on those who fear him,
and he knows every human action.
He has not commanded anyone to be wicked,
and he has not given anyone permission to sin
