For the truth on this matter, see Paragraph #1022 of the Catechism of the Catholic Church, which teaches that each of us "receives his eternal retribution in his immortal soul at the very moment of his death, in a particular judgment that refers his life to Christ: either entrance into the blessedness of heaven-through a purification or immediately, -- or immediate and everlasting damnation."
The bellicose Friendly Atheist, as unamicable as any of his coreligionists, is outraged by a fundagelical's take on this doctrine, as mischaracterized here — Franklin Graham: Carrie Fisher and George Michael Are in Hell (Unless They Accepted Jesus). Says the preacherman, making no reference to the homosexuality of the former or the drug-abuse and promiscuity of the latter, "I hope each of these people had made that all-important decision before they took their last breath on earth." For hoping for the greatest reward imaginable for two public sinners, without even reference to their sin, he is lambasted.
For the fullness of the faith on this matter, see Paragraph #1032 of the Catechism of the Catholic Church on "the practice of prayer for the dead." One might offer this Prayer for the Poor Souls in Purgatory.
