I think not since Satan proved otherwise.
Good try but Satan it's not a human being.
Satan did exercise his free will and sin against God in God's direct presence,
Yes, no purely spiritual being can question God's existence.
But even them once were not able to see God in a way necessary to collapse free-will.
Satan sinned when God revealed Himself to them and the fate of men and the necessary Incarnation.
clearly showing us that it is possible for someone to be in God’s direct presence and still have the free will to sin.
Free-will between God and evil is only possible in a partial God's hidden environment.
This debunks your claim that people cannot have free will while in the presence of God.
Free-will is only possible in a partial presence of God.
Also, Satan committed evil in a place in which there is supposed to be no evil, right in the presence of God.
Partial presence. This is the official position of Catholic Church for centuries. There are no flip-flops in Catholic Church.
If indeed Satan, an awesomely perfect creature, can sin and rebel against God while in heaven, what hope do mere human beings have of not doing the same?
They never were at the same context. But nowhere I said humans cannot follow Satan's decision.
Perfect as in the JW's theology? JW's theology makes no sense. There's no internal consistency.
The awesomeness of Satan's nature (an archangel, one kind among nine kinds of angels) was the reason of his pride. He simply couldn't bear the idea of worship God with a human nature.
So according to what we understand from the devil, human beings should be able to arrive in heaven and still sin.
No.
Satan never was in the no free-will Heaven.
The spiritual world has several levels just like, in a sense, the physical world.
This means that a person can arrive in heaven, commit a sin and God will then condemn them to eternal death.
No.
Eventually, we should expect that everybody will end up in hell.
No.
Wrong premises, wrong conclusions.
ALSO,
If God values free will right up until the point of death when he simply removes free will,
Free-will collapses automatically and naturally. This is a necessary truth.
it doesn’t make any sense for God to create a world in which we have free will.
The purpose of temporary free-will between God and evil is authenticity which is demanded by justice. God is justice.
Think about this chronologically. A person is going to live for eternity, without time. But a person is going to live in this world for approximately seventy years if they are lucky.
So human beings are going to spend a period of time which does not even count as a spec in the ocean of eternity having free will. The rest of the time they will not have any free will. How can it be then that God values free will so highly? It is not logical.
Just because you don't understand the inevitable implications of justice, free-will and authenticity does not means it's not logical.
