It has always seemed to me that Judas had a purpose in life and that was to be the betrayer, and I see this this way because of the man born blind so that Jesus could give him sight to bring glory to the Father. The blind man could do nothing about his condition as only Jesus could do that, and maybe Judas was born to be the betrayer, and could do nothing else, but once done the darkness he lived in lifted away and for the first time realized what had been done, was so remorseful that he could not face himself and took his own life. I would like to believe he asked for forgivness and salvation as he prepared to die.
I join you in hoping that Judas asked for forgiveness. David (Psalm 41:9) and Zechariah (Zech. 11:12-13) both prophesied that the Messiah would be betrayed. But that doesn’t absolve the person who did it. (Matt. 18:7) Knowing the future is not the same as controlling it. I don’t believe that Judas was born to be the betrayer. God knew in advance that someone would betray the Messiah, but I believe that Judas became the one as a result of his own choices.
