There is one important difference - Judas was not born again - he was not filled with holy Spirit. He was not part of the twelve on the day of Pentecost when the Spirit was first given. . . .so he was not "sealed with that holy Spirit of promise which is our inheritance UNTIL THE DAY OF REDEMPTION" . . . . . we are!
Also - the following shows an act of contrition and repentance on Judas' part:
Then Judas, which had betrayed him, when he saw that he was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders, Matt. 27:3
Judas was just as saved as the other 11 disciples of Christ per Lk 6.
Read Matthew chapter 10 and remember that everything said here about the apostles INCLUDES Judas...Judas had the power of the HS to heal, to speak by inspiration and Jesus said anyone that received Judas was the same as receiveng Christ, v40.
Judas died before Acts 2:38 came into effect so he was never held accountable to this water baptism in the name of the Lord for remission of sins, so he was never born again by this baptism.
