Sometimes I really start to believe in conspiracy theories because indeed I feel this world is more evil than I can imagine. And really, the most evil I believe controls the whole world.
You're right, it is hard to imagine what is this Evil. Is it some kind of Demons, or Devils? I've heard other theories as well, but I don't think they explain everything that is happening. This or that group of people or Countries are in charge, might explain some of it, but not everything.
