I only know a very small snippet of their lives from the Bible. It is not my place or anyone else’s to judge others eternal destinies. The temptation is there of course but that is the work of the Lord.
Jesus said of Judas, “it would have been better if he had not been born.” Well, if Judas is in heaven, then Jesus was wrong. As far a Pontius Pilate, it depends on whether or not he ever truly repented and ask forgiveness of God; and most likely he never did, but I cannot say with certainty on Pilate.
