Paul himself was clearly on the Roman side, a double agent and then some...It is quite possible that his conversion by the Zadikites was set up so that he could access secret teachings and betray them.
The man who became the apostle Paul was originally a mercenary hired by the Roman authorities to track down extremist cults such as Zaddikim. In short, he was a bounty hunter. This much is clear even from Acts alone. Time and time again, the Romans protect Paul. They approve his actions and provide him with troops and a personal guard. The Sanhedrin, whose leader at the Jerusalem temple wants to see the Zaddikim suppressed, also sanction the mission of the bounty hunter.
