And now, because of the evil all around us, and moreover, within each one of us, we sin against God and our neighbors. That is certainly true in this world, and that applies to physical processes as well as moral dispositions. Disorder is continually growing as the world moves further away from the time at which it was a perfect system. That is to say, evil is anything which is in opposition to the perfect order that God created. Therefore, pain is evil.
Violent storms are evil.
All orders of things which were not part of the original blueprint for this world are evil. This includes things within the human body, such as evil thoughts, disease, and decay. Evil is inexorably intertwined with existence on this planet. Additionally, it continues to grow as more people voluntarily choose to follow the evil path, and as decay feeds upon itself. In contrast to the seemingly massive scope of evil, exists the idea of sin.
