If you can prove that this scripture is referring to someone other than Judas of Kerioth, have at it.
The scripture already 'had at it', when we are told Satan was in that son of Simon. Satan is that one doomed to destruction.
What would we believe of our precious God were we to accept that God used Judas so as to have Jesus fulfill the mission He was born for, and after Jesus Himself told Judas to go and do what he
must do quickly, if the reward for insuring the final blood sacrifice for the sins of the world was eternal destruction?
Judas repented of the sin he was actually not personally responsible for being Satan was in him. He returned the silver to the elders of the temple who sought to buy the Savior of the world's life for thirty silver shekels of Tyros. They wanted to kill the Messiah , charging Him with blasphemy, to assure their status as leaders of God's chosen. And yet, they used Rome's currency, and their authority to renounce that prophecy fulfilled; Messiah come.
Did they repent of that? Do they to this day? Or are there Jews they'd consider apostate that have become apostate because they know Messiah was Emmanuel.
They walked to Golgotha and watched their plotting unfold to its end. Having insured that it would not be Jesus released as per the tradition just before Passover, of setting one prisoner free, as the Romans bade it happen time and again year after year. And using their authority over their Jewish congregants to chant for release of a zealot and a thief instead; Barabbas. [The Book of Matthew chapter 27]
Judas repented, returned the silver, and put himself on God's mercies as he hanged himself from a tree. Being a Jew, knowing full well what that meant; cursed is anyone who dies on a tree. The Book of Deuteronomy chapter 22.
I believe he was forgiven. Because God tells us it was Satan within him doing these things. And the man when he realized what he had done was ashamed.
Jesus said from the cross, and this for me is key proof of that,
Father forgive them for they know not what they do.
Judas, under Satan's control, did not know what he was doing. But Satan did.
Satan is the son of Perdition destined to destruction. Why do I believe this? Because Jesus chose Judas to be His Disciple. And told Judas in the upper room where the first communion was to take place, go and do what ye must do quickly.
Satan cannot do anything God doesn't permit him to do. The Book of Job chapter 1.
