Many wonder if sin is an attitude or an action or a situation or a result, and the answer is that all these combined together make either a virtue or a sin. The absence of one from it makes it incomplete, but all these together make it a complete virtue or sin. Now, the question is where it is originated, what is the source of it, and the answer is that its origin is in wrong thinking. Wrong doing comes from wrong thinking and wrong thinking comes from wrong feeling.
