It is recorded in the bible that Judas hanged himself after betraying Jesus. I used to wonder what if Judas did not hang himself, then he saw the resurrected Jesus a few days later, and sought for forgiveness. Would Jesus say “Judas! I will not forgive you!” or would He forgive Judas?
Pastor reminded me that when Jesus died on the cross, He died for us and our sins, and that includes Judas and his sins. Hence if Judas sought for forgiveness, Jesus would forgive him. That is also His grace for mankind.
