John 17:11-12

John 17:11-12. And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one as we are. While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of Perdition; that the scripture might be fulfilled.

So it is clear that Judas was not amongst those who were given to Christ by his Father; if he had been, he also would have been "kept."
