From subatomic particle to super cluster, the universe is a series of interacting systems nested one inside another. It is a single set of systems ruled by a single set of laws. We are but pieces, parts of a whole scattered across its constants. Evil began when someone got stuck on a problem and took it out on others, creating the same problems for them. Since that time it has tumbled down through the generations, changing as we change, evolving as we evolve.
Unsolved problems are perpetuated problems.
They survive their host and harm life. This disease reproduces . It is predictable. It follows patterns. It has a known life cycle and describable process of transmission.
