(Matthew 27:3): Then Judas, who betrayed him, seeing that he was condemned, repenting himself, brought back the thirty pieces of silver to the chief priests and ancients…
Scripture says that Judas was sorry for his own sake, which seems to suggest that he lacked supernatural sorrow and charity. If he is lost, it is because in his final moments he did not turn to God with repentance.
Many saints and mystics believe that Judas died impenitent. Bl. Battista Varani believed that Our Lord revealed the following to her (I share these words because, while sad, they also reveal Christ’s love and tenderness):
"When I saw the design of betraying Me forming in his heart, I redoubled the proofs of My tenderness, to turn him from his criminal thoughts, but it was of no avail; nothing would touch his wicked heart. On the contrary, the more affection I showed him, the more he was hardened in his perfidious resolution. When, at the Last Supper, I performed the humble and touching ceremony of washing My disciples’ feet, My Heart could not contain itself; but I wept bitterly, and watered his polluted feet with My tears, for I said within Myself: “O Judas! what have I then done to you, that you should betray Me thus? O unhappy disciple! is this to be the last proof I shall ever be able to give of My love for you? O son of perdition! why dost thou leave Thy Father and Master? O Judas, if you would have thirty pieces of silver, why not go and ask them from My Mother thine; she would sell herself to free thee and Me from danger and death. Ah! ungrateful disciple, today I wash thy feet, and kiss them with so much love, and in a few hours thou wilt kiss My Face, to deliver Me up to My enemies. O dear and beloved son, what a return thou makest to One who weeps the loss of thee more than His own Passion and death, because for this He came into this world.
While My Heart was speaking thus, My tears watered his feet, but he saw them not, because I was kneeling before him, My Head bent down, and My long hair falling about My Face, so that he could not see My tearful countenance. But John, my beloved disciple, to whom I had revealed all the mysteries of My Passion during this sad Supper, observed My every action, saw My tears flow on the feet of the traitor, and understood that they proceeded from the tenderness of My love. When a father sees his only son about to die, he is eager to serve him, and says in his heart, “Farewell, my son, this is the last service I shall be able to render you.” Thus did I act towards Judas, when I washed and kissed his feet."
