If you have a bus, a train or a plane that is traveling and is filed by wicked passengers, you can smell danger. It may not arrival safely. It is hard to know what a wicked passenger can do. Such a passenger can even shatter the bus, the train or the plane with an explosive and die with others. In fact, there are people who do this.
When I think of this, what comes to my mind is the world in which we live. It is like a bus, a train or a plane taking us to our earthly destiny which is our earthly destination. Because the world has so many wicked passengers aboard its vehicle, the world is as turbulent as it is. The wicked passengers are making life unbearable for many. They are killing, cheating, exploiting, suppressing, violating human rights etc.
Wicked passengers on our earthly plane are the force behind the so much evil in the world.
