Judas had the authority and the opportunity

Judas Icariot is so interesting. This guy was given every opportunity. Judas was, apparently, even given the healing and exorcism powers that the other disciples demonstrated...

And he called to him his twelve disciples and gave them authority over unclean spirits, to cast them out, and to heal every disease and every affliction. The names of the twelve apostles are these: first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother; Philip and Bartholomew; Thomas and Matthew the tax collector; James the son of Alphaeus, and Thaddaeus; Simon the Cananaean, and Judas Iscariot, who betrayed him. (Matthew 10:1-4)

So, did God harden Judas' heart like he did Phaorah, so that Judas could serve his intended role? Or did Judas successfully resist Jesus calling? Or did Judas begin true and then something turned him? In any case, there, but for the grace of God, go I.
