Judas, who would betray him, answered, “Is it I, Rabbi?”
He said to him, “You have said so.” (Matthew 26:25)
Great question. The Christian Apologetics and Research Ministry (CARM) answers this question HERE. The author states: "God knowing what we are going to do does not mean that we can't do something else. It means that God simply knows what we have chosen to do ahead of time. Our freedom is not restricted by God's foreknowledge; our freedom is simply realized ahead of time by God."
So Jesus predicted that Judas would betray him (Matthew 26), He is not violating any free choice. He is only stating what Judas will choose. To answer your question directly, Judas could have had a change of heart, but he chose not to - and betrayed Jesus for thirty pieces of silver. Ironically, Scripture tells us that Judas actually had a change of mind AFTER Jesus was crucified: "Then when Judas, his betrayer, saw that Jesus was condemned, he changed his mind and brought back the thirty pieces of silver to the chief priests and the elders" (Matthew 27:3).
