I do see our world in a major struggle. This beer bug was most definitely one of the final steps to implement a New World Order. Until now there was a power struggle between the government and the people. Sometimes the government forced their will, and other times the people were able to resist. This bug added a whole new perspective with a lens of fear. This fear has divided people on all levels. Families, friends, coworkers and neighbors are divided. The Powers That Were know that fear is a tool, and they also realize that divided societies are weak.
With regard to the Beast, yes, this bug created a gateway for the Beast to enter. I see this is being done by the faction supported and forcing the shot. This shot will forever change people, their offspring should they be able to reproduce and their connection to their inner god. This Beast has also opened up the pathway to rob people of their rights in such a way that they are voluntarily forfeited (emotional manipulation is in full force).
