To my understanding the word Satan in Hebrew is translated as "adversary". So... I think the more you see adversaries or enemies out there in the world the more you will have "Satan" in your life.

I really like this view point. Resonates with the teachings of Jesus as well.

If you can learn to see that virtually everyone is struggling in their own ways and that virtually everyone is doing what they think is best for themselves even if it seems evil to you... Then, I think you will likely be much closer to true peace within yourself even if the outer world is still very chaotic.

One of my favorite philosophies is Ubuntu. A term that came about in South Africa and Zimbabwe roughly translating to "I am, because we are". I find it keeps me grounded when thinking of great "evils". They've been sculpted by their own experiences just like you or me, unfortunately those experiences lead them down an awful path. But its a path that any of us would have also went down given the same experiences and brain chemistry.
