Subjective or personal realities need to be narrowly limited to individuals. Outsiders cannot properly relate to someone else's subjective and personal realities.

Therefore, evil persons do the opposite in their attack upon life. They focus upon the most subjective and personal realities as a method of doing the most harm. By subjectivizing their war against life, evil persons gain an advantage—a fool-proof method of winning—because normal people do not do that. Subjective, personal realities are off limits socially.

Evil can be defined in that manner. It's doing what normal humans do not consider to be acceptable. Focussing on subjective, personal realities is the most extreme method of doing what humans do not allow. Of course, imperfect humans do a little of what evil persons do but not so purposefully and systematically.

Evil is a vengeful retaliation against the life that rejects corrupters. There is some attempt by evil persons to reconstruct a state of existence which is less problematic for them. It is not credible; so the reaction is to attack the unacceptable normalcy of human life.

Evil evolves as counter-reality, counter-intentions and counter-forces. Whatever others do not want them to do is what evil persons consider to be the most effective means of attacking them. Through counter-everything, evil persons focus upon the most subjective and personal realities of their opponents. There is no real defense, because subjective and personal realities cannot be fought over in the public domain.

This is why separation of church and state is necessary. Religion is too subjective and personal to be fought over in the public domain. Government must have a more limited role in making life possible rather than arbitrating how it is lived.

Where there is darkness, evil always prevails. It takes openness and accountability to defeat evil, because the power of truth is the only force corrupters cannot subdue. The power of truth cannot be developed without openness and accountability.

So where darkness allows evil to prevail, there is subjective attack upon humans. At its extreme, it means torture in the prisons. Rational persons try to objectivize confinement such as prisons, while evil persons use confinement for personal attack such as torture. The jails and prisons have so much darkness in every country including the U.S. that personal degradation is always a part of the process. Even when rational persons try to improve conditions in the jails and prisons in the U.S., they fail, because evil rules the dark.
