OT Pseudepigrapha-false writings but purposeful

In last class, when we were learning about the OT pseudepigrapha i thought it was interesting how transmission of the OT actually was only beginning a little before the pseudepigrapha. It must have been hard to discern real from the truth. All these ideas were circulating and indoctrinating the people with something that was not the truth. I do believe that these texts though that proclaim a falsehood do serve a purpose. They illustrate the mindset of the people in their expectations for a messiah. If the messiah was expected to be as Jesus was how would things have been different. Would Jesus have been crucified? I can't help but be amazed at the way God uses everything for his purpose, the bad and the good.
