Satan has only one objective. To destroy God's creation. Depopulation the biggie. He doesn't care how it gets done, only that it does. Getting a large portion of the human race to destroy the rest by any means possible is fair game. Thankfully for Satan, humans are easily led around by the nose and deceived. This is why it's not only important to be awake, but to stay awake. Satan and his work has never had any trouble infiltrating any group or movement. The fastest easiest route is through the lower levels of the group or movement at first. Confirmation bias is one of his best tools. It's a constant chore and often unpleasant to maintain staying awake when all most of us want is just some relief and peace. You will suffer this unpleasantness and know his workings when the people who are on the same side as you visa versa tend to go off the deep end butt hurt should you see something and say something. And people wonder why so many of us just don't care to participate anymore and concentrate on survival. Unfortunately for Satan, God always wins. So survival and trying to stay out of the line of fire is not unreasonable.
