Would the Devil steal from his brothers then betray believers in Jesus?

I believe the Devil definitely would, where this happened to Jesus in the Gospel of John 12:4 and Judas was his betrayer. Thieving money out of the treasury is what Judas being in charge of the money did, and the bigger the thief the bigger the betrayer, where the Devil would sell all believers to the enemy there's no doubt about that; Jesus makes believers in him aware though of what he's up to which has to be a good thing; the tone of the Devil is so convincing and righteous most of the time though that it's very difficult to realise that betrayal is going on, until God the Father through his son with the Holy Spirit tells believers, in all different loving ways. Mankind needs to run from the betraying Devil, but this is really really difficult due to the Devil's cunningness, and like Jesus says in the Gospel 'get behind me Satan' is really only mankind's way of defeating the Devil. The Devil just yawns at mankind because he finds it so easy to deceive and betray, to steal what little good they have in them, then turn them over to the enemy. The Devil will betray Mankind to the enemy, Jesus would never do that. (My knowledge and Trinity beliefs in the Holy Bible.)
