That was Oscar Wilde's argument , that Judas was the one true sacrificial lamb:
Someone had to betray Jesus for gods purpose to be fulfilled
Satan entered him, like Adam it was Satan's fault
So Judas therefore had no freewill..he was a pawn
Unlike Jesus' temporary death, Judas' death is permanent
Therefore it's Judas we have to thank for our salvation.
If, of course, any of it is true.
These 1st century Jews were not the best philosophers....let's face it their reasoning is easily taken apart. This 300 years after Socrates death too...very poor show!
