As Aristotle alluded to, a man who does not enjoy the act of doing good deeds is not a good man; thus, for a virtue to exist as a virtue, it must stem from love and thus love must be the supreme virtue from which all others branch.
The confessing codes need a master to handle them. They cannot be interpreted by one who is an amateur of the craft. Everybody confesses everything, their deepest crimes and fears in everyday language. For a code-breaker it is simple to follow the trail and expose them all. Gemma was one of the linguists who could break them. Some saw what she did as magic, yet in truth she was partnered to the positive universe, a tool of the divine force and saw nothing special in herself. She was as natural as the trees and the fish in the oceans. Yet in the "junk" speech, the ad libs and the stories people tell, in their creative flourishes, there are clues. Much is actually junk, fears of nothing and misplaced guilt, yet a master such as her could tell what was real because the universe placed flags only she could detect, shone lights that only she could see. It was as if her soul shone a black light and the criminals were marked in some invisible ink. She was the ultimate detective, the one sent to uncover the hidden world of vice, sent to restore true virtue.
Humanity, dear one, has been lovingly evolved by our creator as an apex nurturer rather than a predator. The genocidal roots in every human are simple to trace, yet our story is one of cooperation and love also. It is the story of our inner struggle between virtue and vice. The apex nurturer has learned virtue. The apex predator has learned vice. Each believes their values are superior. The path of virtue will lead to a heaven on Earth. The path of vice will lead to a hell on Earth. So, take your own inner battle to become a good person with all seriousness, your task to learn true virtue... the future of the world depends upon it.
