It was Cainites who later became the much famed "Jewish Bankers" of the middle ages which only brought real Jews all the more hatred with people again thinking Jews to be the 'children of the devil' never realizing the two clear distinctions between Cain and Seth.
It was Cainites who created "The Protocols of Zion" which was their obvious and now open attempt to expose the 'evil jews' when in fact it was they who both created and circulated the mysterious document, the work being their own plan to bring a 'bloody despot King of Zion' (the Antichrist) and never was it an agenda of the more innocent Jew who have as their heart to believe in a future Messiah.
