I don’t really see your theory in Scripture at all.
Judas is portrayed as being part of God’s plan. Christ knew that Judas would betray him.
I have to agree Salvation...I’ve never read that in scripture either.
It’s really a matter of semantics. Was Judas initially an apostle because he loved Jesus? Probably. Did he have other motives as time progressed? Probably. If Judas eventually used Christ for political motives then, yes, he did betray him. Did Judas believe or intend that Christ be killed? Well, that’s a big question. Obviously, since he killed himself, he apparently felt some guilt.
