4. Christian faith teaches that in taking the risk of saying “yes” or “no”, which marks the human creature’s freedom, some have already said no. They are the spiritual creatures that rebelled against God’s love and are called demons *(cf. Fourth Lateran Council, *DS 800-801). What happened to them is a warning to us: it is a continuous call to avoid the tragedy which leads to sin and to conform our life to that of Jesus who lived his life with a “yes” to God.
Eternal damnation remains a real possibility, but we are not granted, without special divine revelation, the knowledge of whether or which human beings are effectively involved in it. The thought of hell — and even less the improper use of biblical images — must not create anxiety or despair, but is a necessary and healthy reminder of freedom within the proclamation that the risen Jesus has conquered Satan, giving us the, Spirit of God who makes us cry "Abba, Father!" (Rm. 8:15; Gal. 4:6).
(Italics are mine.) It seems pretty clear here that Pope JPII is saying that not only don’t we know which humans are in hell, but we also don’t know *whether *humans are in hell. Demons are (or will be) in hell, yes. But humans? – that’s not known.
