Not sure what you are reading there that says they are in heaven?
His “confession” to Our Lord made him “perfect.” His death on the cross was his purgatory. Only God knows our hearts completely. God Bless, Memaw
And we know for sure they are NOT in Hell. God Bless, Memaw
Was Satan a good angel in heaven when he committed his sin of disobedience?
He was a good angel when he was created but the angels were not yet in Heaven. Satan never saw Heaven, He rebelled against God and never made it there. The “Good” angels did go to Heaven after their test of obedience. When a soul is in Heaven, angel or human, it is perfectly happy. Who would ever want to give that up???No one ever sins once in Heaven. God Bless, Memaw
God impels us to righteousness, virtue and holiness by giving us grace. "Give us the grace to will and to accomplish, motivate me to do the things I should do. "…lead us not into temptation, do not allow us to be tempted, or to succumb to temptation. Lord move me from the capacity of not having or being virtuous or holiness, to being virtuous or holy. It is the Holy spirit who sanctifies, we do not sanctify ourselves. We can not give what we do not have, the fruit of grace. What God requires is our willingness to co-operate with His grace. I can’t will perfection, it is given. Holiness was given to us when we were baptized into Christ, and even though we were not given spiritual maturity we still are saints to be matured by the practice of virtue. There would not be growth in sanctity if we didn’t have a capacity (potential) to grow (act) The soul is not it’s own power. and God is the mover of the will to sin or to practice virtue, He respects our right to choice since He gave it , and will back up our choice even if it is sin, even when He doesn’t will us to sin. By his will man can oppose God to his own destruction, having a capacity for good or evil, what will be his choice, what will be his acts? Potency and Act are not the same and we are constantly moving from potency to act in the material world, and the spiritual world
Do humans have free will in heaven or is it taken away from them?
That is not what Jesus tells us: Jesus says that He saw Satan falling from heaven like lightning.
Heaven? Or THE heavenS - as in, the sky? As in, falling to a lower existence the same way lightning falls from the physical sky. Someone already pointed this out elsewhere.
Maybe it’s because poetry is a lost art than no one understands metaphor anymore. 
Protestants say that Roman Catholics do not understand that the Eucharist should be a metaphor and not taken to be the literal Body and Blood.Heaven? Or THE heavenS - as in, the sky? As in, falling to a lower existence the same way lightning falls from the physical sky. Someone already pointed this out elsewhere.
The Bible tells us differently. It specifically says that Satan of the dragon was cast out of heaven. In fact there are icons of St. Michael the archangel doing such.
Satan was called “Lucifer” the barer of light, next to the throne of God before the fall. According to church teaching on the devil are (a) God created the angels who are good by nature, some sinned and deliberately became bad; (b) it is not the devil who created matter and bodies; (c) Satan and his followers were punished by God by being cast into hell, whence they insidiously ensnare and persecute men, but only in so far as God permits; (d) the devil, like all the angels, are pure spirits endowed with intellect and will; (e) these pure spirits WERE WITH GRACE FROM THE FIRST INSTANT OF THEIR CREATION: many fell into a sin of pride and lost irremediably because, due to their spiritual nature, ONCE THEY HAVE MADE THEIR FREE CHOICE BETWEEN GOOD AND EVIL THEY ARE IMMUTABLE IN THEIR WILL AND SO WITHOUT THE POSSIBILITY OF REPENTANCE. ; (f) the devil by sinning lost his supernatural gifts, but he retains his spiritual nature, rich in intelligence and in will tenaciously bent on evil; (g)the devils hate men who are destined to replace them in Heaven.
When Jesus said “Unless you drink my blood, and eat my body, you shall not have life within you” some of those who heard said that this was a hard saying and walked away And Peter, said “You have the words of everlasting life” True Christian Catholics believe in the mystery of the “Transubstantiation” that Jesus is truly present at the consecration of bread and wine, into the body, soul and divinity of Christ. There are many recorded miracles surrounding this mystery, I am witness to the truth of this Mystery.
Which is my point. Now, do humans have free will in heaven?
Human have free will in heaven, the will of man finds the total Good in God since the appetite of the will of man is for the Good. Once at rest in the total Good, there is no further desire for anything else, for it is satisfied in its quest for the Total Good who is God Free will is always in pursuit of Happiness as it perceives it, some only perceive it in created goods, creature goods but these things in themselves never completely satisfy, because man was created for the Eternal Good, when acquired the will makes no other choice because it is completely satiated, and it still remains truly free and secure in it’s freedom, it is freedom without the hinderence of the possibility of choosing a lesser good.
So you do take that saying literally?
How can you be free if it is impossible for you to choose sin? If you can be free in that sense, then why did not God make us on earth free in that way?
Not free to chose… eh I disargee with the presentation.
