When they come to see the cross, and the nails, then they will understand, and then....
What then?
He catches sight of the panic-stricken Thomas in passing, and for some reason or other reassuringly nods to him; he overtakes Jesus being led to execution.

The walking is difficult, small stones roll under the feet, and suddenly Judas feels that he is tired.

He gives himself up wholly to the trouble of deciding where best to plant his feet, he looks dully around, and sees Mary Magdalene weeping, and a number of women weeping--hair dishevelled, eyes red, lips distorted--all the excessive grief of a tender woman's soul when submitted to outrage.
Suddenly he revives, and seizing the moment, runs up to Jesus: "I go with Thee," he hurriedly whispers.
The soldiers drive him away with blows of their whips, and squirming so as to avoid the blows, and showing his teeth at the soldiers, he explains hurriedly: "I go with Thee.Thither.Thou understandest whither." He wipes the blood from his face, shakes his fist at one of the soldiers, who turns round and smiles, and points him out to the others.
Then he looks for Thomas, but neither he nor any of the disciples are in the crowd that accompanies Jesus.

Again he is conscious of fatigue, and drags one foot with difficulty after the other, as he attentively looks out for the sharp, white, scattered pebbles.
When the hammer was uplifted to nail Jesus' left hand to the tree, Judas closed his eyes, and for a whole age neither breathed, nor saw, nor lived, but only listened.
But lo! with a grating sound, iron strikes against iron, time after time, dull, short blows, and then the sharp nail penetrating the soft wood and separating its particles is distinctly heard.
One hand.

It is not yet too late! The other hand.
