The Concept of Sin

Sin is a conscious decision.  This is the definition my cloistered brothers deduced, in our study group.  We are reading Josef Pieper's The Concept of Sin.

Sin is a failure to act normal.  It is deviant.  It is just not the way human beings should act.  Pieper says the same thing Aquinas says.  " Every sin is contrary to nature."  That the root of sin is pride (superbia) and desire (cupiditas).  We thought money was the root of all evil, but wouldn't the acquisition of money be a source of pride?

Sin is an interesting subject.  Here is a question left unanswered; if sin is contrary to human nature, then how come sin is such a natural desire?  Or is it?
