Concerning the fate of Judas, the following statement appears in Basics of the Faith: A Catholic Catechism, by Alan Schreck (Servant Books): “The Catholic Church teaches that we cannot judge or determine whether any particular person has been condemned to hell, even Hitler or Judas Iscariot. The mercy of God is such that a person can repent even at the point of death and be saved.”
An American Catechism, edited by George Dyer (Seabury Press), however, says of despair that it seems to be: “Besides a distortion of faith itself, more a psychological and emotional crisis, perhaps generated by past sins, than a mortal sin in itself. Obviously despair is a grievous matter.
“But it is very difficult to conceive how a person who despairs could fulfill in this act the other conditions requisite for mortal sin. It is particularly difficult to believe that a person who despairs does so with full consent of the will or in a radically free act.”
