Judas is often identified as a Zealot, an attribute held by only one other disciple, Simon the Zealot. We know that Judas was probably a Zealot by his surname, Iscariot. Researchers believe this is a form of the title sicarii, meaning "dagger-men," a group of ultra-Zealots who carried a knife with them at all times to be prepared to assassinate traitors and capitulators. In English, we could call him Judas the Daggerman.
Though motivated primarily by socio-economic and political factors, the Zealots also had prophetic ideas driving them. They believed that if they turned Israel back to God and incited war against the Romans, the Messiah would arise to lead them and establish His Kingdom. This "understanding"resulted from misinterpreting many prophecies concerning Christ's teachings. In short, the Zealots ignored many of the prophecies regarding His first coming and completely mis-timed those about the second.
