Superiority had many uses. Chief among them was providing inarguable justification for doing whatever was needed in order to guarantee that "enough" of everything—including God's love—was available. Knowing the conditions gave one the right to ignore others, or seek to convert others, or simply eliminate others who did not know the conditions, or agree to them.
Therefore, seeking to know the conditions of Life became a major preoccupation. Knowing the conditions of Life was called science. Knowing the conditions of the afterlife was called conscience. If one knew these conditions and understood them, one was said to have "a good conscience," or to be "conscious"
A "high consciousness" was said to result from the earnest study of something you called theology, from theology, or, loosely, God logic.
After much study, it was concluded that there were certain circumstances under which the Requirement could be met, and certain circumstances under which that was impossible. There were also certain circumstances under which one could be forgiven for not having met the Requirement.
These circumstances came to be known as "the conditions."
"Having" was added to "doing" in your experience.
When you have enough brains, you can do the thing called get good grades, graduate at the top of your class, and find a great job. Then you can be the thing called successful.
When you have enough money, you can do the thing called buy a wonderful house, and you can be the thing called secure.
When you have enough time, you can do the thing called take a vacation, and you can be the thing called rested, refreshed, and relaxed.
When you have enough power you can do the thing called determine your own destiny, and you can be the thing called free.
When you have enough faith, you can do the thing called find God, and you can be the thing called saved.
This is how you set up your world.
The more knowledge of these conditions one acquired (or was thought to have acquired), the more superior one was understood to be.
As has been mentioned, this Superiority gave people he authority (or encouraged people to grant themselves the authority) to do whatever they felt was necessary in order to assure themselves more Life and more God— neither of which there was enough of.
This is why you've had to do what you've had to do: because there was not enough. This is what you have told yourself. Your entire species has accepted this mantra.
