If we use the Bible as our guideline to determine someone's guilt and eternal damnation, or innocence and eternal salvation, we will find both, damnation and salvation for Judas. In fact, if we try hard enough using some JW ingenious reading and interpretation techniques we may even "find out" that Judas was Jesus lover and did what he did because he was jealous of Peter.
Wow! I had to edit and add to my comment after I clicked the link above (sir82)
Possibly Bart Erhman had the same thing in mind (Judas and Jesus as lovers). Look how closely Judas' lips are to Jesus' lips in the cover of his book.
In a more serious note: "Judas did not show true repentance" Really? the poor man took his life right after the "sale". Besides, it was God who crafted the whole story. God is the one who needs to show repentance for his filicide.
