What is SIN? The nagging voice in the back of your head that reminds you of your mother when you were bad as a child?
What is SIN? The action that you repeat only to find the same result in the end as the last time you did that same exact action?
What is SIN? An obligation to something greater than yourself that was broken or just an obligation to yourself which was forgotten?
What is SIN? A cruel master that forces you to be unhappy because you fear the unknown and you need someone else to tell you what to think?
What is SIN? It is being NOTHING. Not leaving a MARK. And having the world forget you ever existed, much like a single speck of sand in a dust storm.
