Let's say yes he repented and did not want nothing to do with evil again and then killed himself in remorse.
Satan at that time, had the keys to Heaven and Hell. (Not anymore now, Rev 1) Satan could put people in Spirit prison and did. I see Judas, got put in Spirit Prison, along with all those others that were there waiting in belief, no matter how long it took to receive (Hebrews 11). These, stood in belief to God's Son, the Messiah coming. Was Judas a witness, when Jesus arrived there not long after Judas killed himself? You do need at least two witnesses, right? Jesus and Judas revealing God Father
1 Peter 3:18-19
King James Version
18 For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit:
19 By which also he went and preached unto the spirits in prison;
Then, on that third day
Matthew 27:52
King James Version
52 And the graves were opened; and many bodies of the saints which slept arose,
That is only reported by Matthew, it is not in other texts
Yet, God saved Peter, who denied God, did God not? Yes, therefore God in love and mercy saved Judas too, IMHO
The God I know, is a lover of our souls, wanting what is best for us all (Jeremiah 29:11) therefore repent to God (Change your mind and believe God just loves thee also)
God will set you free in his risen Son for you, once you agree by that one time death only, you are reconciled as 100% forgiven forever by God through Son for you too. (2 Cor 5:17-20)
No second guessing, as man has been doing, even after the resurrection fro us to be saved by, not by any flesh work.
It is done for you and all the world to believe God or not.
1 John 2:1-2, verse 12, Chapter 4. Eph. 1:6-7,13, Phil 1:6, Amazing grace to appreciate and ask God for the new life, Son gave to give us in his risen life, not the dead one, having gotten given this, one can't help but love all, the same as Jesus did on that cross willingly. Having the "Art of fighting without fighting". So you going through people, one or many others, are at your throat in giving you troubles. =Okay say thank you, being now content in all things seeing. the only thing that over comes, overcame evil is Christ the Son
Romans 12:21
Be not overcome of evil, but overcome evil with good. Is that not what Christ did? Who is risen and those that got him killed saw him risen as in Col 2 tells us this truth?
