I'm saying that Judas did not accept Gods forgiveness, he relied on his own good deed of returning the blood money, 'woe to him who has seen the Son of Man and has not believed', Judas was a thief tried and true.
No way is it wrong to try to give back the money. There was a thief in the Bible who gave back money and it was okay.
We have to be sorry about our sins and repent of them.
Judas was obviously sorry and he repented, but there was no way he could believe he would be forgiven.
Note that Jesus had also called Peter 'Satan' because Peter was attempting to rebuke Gods plan through His Son, Peter also denied ever knowing Christ three times and Christ forgave him those three times by asking if Peter loved him!
Well there are some big differences from Peter and Judas.
Peter made a mistake by not understanding that Jesus had to die and that Jesus was not coming to get at anyone; in addition, Peter denied Jesus out of fear of physical harm. That is way different than Judas.
This is a prime example of how God will never leave his people!
Judas however failed miserably by repenting for himself and purchasing for himself a lot,
Matthew 27:3 Then Judas, which had betrayed him, when he saw that he was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders, 4 Saying, I have sinned in that I have betrayed the innocent blood. And they said, What is that to us? see thou to that. 5 And he cast down the pieces of silver in the temple, and departed, and went and hanged himself. 6 And the chief priests took the silver pieces, and said, It is not lawful for to put them into the treasury, because it is the price of blood. 7 And they took counsel, and bought with them the potter's field, to bury strangers in. 8 Wherefore that field was called, The field of blood, unto this day. 9 Then was fulfilled that which was spoken by Jeremy the prophet, saying, And they took the thirty pieces of silver, the price of him that was valued, whom they of the children of Israel did value; 10 And gave them for the potter's field, as the Lord appointed me.
completely abandoning his trust in God. If he were a true martyr as all of the Apostles and disciples were (give or take John of Patmos) he would have not so easily been replaced imo... and he would not have taken his own life
He was chosen because he was not good and would betray Jesus.
