Judas went out of way to betray Jesus and after making his choice regretted it but what does he do? Go and ask forgiveness?

That's an argument from silence, but all indications are that he was unable to repent, even though he knew what he did was wrong. He was God's fall guy. Where does Judas not exercise his free will?

Read Luke 22:2-4. Judas betrays Jesus while possessed by Satan, in order for God's plan to stay on course, and on time.

[count-your-change]

In vs. 6 Luke says Judas sought out opportunites to betray Jesus and John says Satan entered Judas also just before he left at the end of the Passover meal.
By the time Judas went to the chief priests he was already corrupt. He feigned a concern for the poor while stealing from the money box. (John 12:6)
In fact at Capernaum Jesus calls him a devil or slanderer.(John 6:70)

So Satan was not entering a clean vessel here. A “fall guy”??? He realized his actions were wrong, meaning he knew the difference between right and wrong. He knew what he was doing. Unable to repent? Matthew 27:3 saya he did repent. Possessed? or Influenced or guided?

“Read Luke 22:2-4. Judas betrays Jesus while possessed by Satan, in order for God's plan to stay on course, and on time.”

Whatever Judas or Satan did His plan would do as He wished.
