Thousands of years ago when I was a teenager and a brand-new Christian, I happened to read an article by S.G.F. Brandon about Jesus being a Zealot, in which he questioned much if not most of the Gospel portrait of Jesus and suggested that the Gospels (particularly that of Mark) constituted a whitewash of Jesus, eliminating His Zealotry from the Gospel picture to make Him and His movement more acceptable in Roman eyes. It was, of course, a precis of his 1967 book Jesus and the Zealots which created something of an academic dust up in its day.
