Why not just destroy the damned thing??
First off, I would like to say that this movie is really, really bad. The script was just awful, the special effects were bad etc. I only liked the "Stiffmeister" because I loved him in all three American Pies. But I digress.
The writers of this piece of crap never even bothered to mention a reason why the monks simply did not destroy the scroll in the first place. If it was so terrible, if it fell into the wrong hands they should have destroyed it, and that would be the end of that. Of course, if they did, there wouldn't be a movie. Which can only mean two things (both of them are good), there would be an entirely diffrent movie (anything would be better than this) and the other being there really is no movie, I think that would be the best for all concerned. :-)
