There are natural laws of the universe but there are no rules and regulations.
All moral laws are man made, and they are, at best, pretty shaky.
It wasn't too long ago that torture was legally used by both church and state to elicit a confession. That is as one-sided as dunking a suspected witch under water for several minutes. If she drowns, she's innocent. Because there is no separation of consciousness once we withdraw from the illusion of the physical world and it becomes horribly apparent that what we do to another living being we are doing to ourselves, there are two guidelines to the universe that we would do well to follow. Do not violate life other than for sustenance, so do not violate nature, and do not violate the earth.
