The entire universe exists as the body of Zykna. Every star, planet, tree, etc. is an organ within Zykna's form. In this way, everything is connected with a collective conciousness.
The only "sin" to exist is deliberately or carelessly harming the collective conciousness, by bringing harm to another or many concious, separate living beings.
No one person is purely evil or purely good. It is measured on a scale when one meets Dozam, of the good against the bad, with the neutral. That is what determines what plain a mortal is sent to after death. Dozam cannot be bargained or pleaded with.
