Introduction:
Judas Iscariot, one of the twelve apostles of Jesus Christ, is a figure whose actions and reactions have been the subject of much theological discussion and analysis. His reaction to various events, particularly his betrayal of Jesus, provides insight into his character and the fulfillment of biblical prophecy.

Betrayal of Jesus:
Judas Iscariot is most infamously known for his betrayal of Jesus Christ, an act that was prophesied in the Old Testament. In the Gospel of Matthew, Judas agrees to betray Jesus to the chief priests for thirty pieces of silver (Matthew 26:14-16). This act of betrayal is a pivotal moment in the Passion narrative, leading to the arrest and crucifixion of Jesus.

The Last Supper:
During the Last Supper, Jesus reveals that one of the disciples will betray Him. Judas's reaction is one of feigned innocence, as he asks, "Surely not I, Rabbi?" (Matthew 26:25). This moment highlights Judas's duplicity and the fulfillment of Jesus' foreknowledge of the betrayal.

Regret and Remorse:
After Jesus is condemned, Judas experiences a profound sense of regret. Matthew 27:3-4 states, "When Judas, who had betrayed Him, saw that Jesus was condemned, he was filled with remorse and returned the thirty pieces of silver to the chief priests and elders. 'I have sinned by betraying innocent blood,' he said." Judas's reaction here is one of deep remorse, acknowledging his sin and the innocence of Jesus.

Return of the Silver:
Judas's attempt to return the silver signifies his internal turmoil and recognition of his wrongdoing. The chief priests, however, dismiss his plea, stating, "What is that to us? You bear the responsibility" (Matthew 27:4). This response leaves Judas isolated in his guilt.

Death of Judas:
Overcome by despair, Judas's final reaction is to take his own life. Matthew 27:5 records, "So Judas threw the silver into the temple and left. Then he went away and hanged himself." This tragic end underscores the gravity of his betrayal and the depth of his remorse.

Theological Implications:
Judas's reactions throughout these events have been interpreted in various ways within Christian theology. His betrayal is seen as a necessary part of God's redemptive plan, fulfilling prophecies such as those found in Psalm 41:9 and Zechariah 11:12-13. Judas's remorse and subsequent suicide raise questions about repentance, forgiveness, and the consequences of sin.

Conclusion:
Judas Iscariot's reactions to his betrayal of Jesus Christ are complex and multifaceted. They serve as a somber reminder of the human capacity for sin, the weight of guilt, and the fulfillment of divine prophecy.
