Who said anything about intimacy. David's faith was still in God, when he went through the whole affair [no pun intended] wiht Bathsheba and Uriah. Peter's faith was still in Christ when he denied Him. He was scared, but he did not lose faith. I may even be able to say the same about Judas, but I don't know for sure about what happened to him.
Judas was chosen after prayer to be in the inner circle. Jesus did not chose a devil. He chose a disciple. Judas fell away from grace and died as a son of perdition/hell. He refutes your idea that he was never a believer. The other loop hole is to say this was before the resurrection. The reality is that any believer, OT or NT, can become an unbeliever by choice or rebellion. OSAS is a false assurance for those who live like the devil while claiming a previous Christian conversion.
