Who was the Wicked Priest of the Dead Sea Scrolls?

Answer 1

I think your referring to the scroll of the sons of light and the sons of darkness.

If that's what you are referring to then the Wicked Priest would be the high Priest of the Temple in Jerusalem.

the people of Qumran saw themselves as the keepers of the true faith that would bring on a messianic age and defeat those who stood against them with the help of G-d.

Answer 2

I don't know of any.
