Did Judas deserve this fate? If Jesus informs you that you will betray him, and tells you to hurry up and do it, are you really responsible for your act? Furthermore, if your act sets in motion the process—Christ’s Passion—whereby humankind is saved, shouldn’t somebody thank you? No, the Church says. If you betray your friend, you are a sinner, no matter how foreordained or collaterally beneficial your sin. And, if the friend should happen to be the Son of God, so much the worse for you.
