Sin is not something man does by accident. It is something man does or allows based upon an unwillingness to stop an act before it becomes sin.
Scripture provides examples of specific sins; however, no example DEFINES sin. John's first epistle defines it as the transgression of the law.
Loyalty is a godly trait, and like most godly traits, difficulties can accompany it. The story of David and Uriah serves as a prime example. David sinned against the Lord when he committed adultery with Bathsheba, Uriah’s wife. His actions caused her to become expectant with child. In an attempt to cover his wickedness, he sent for Uriah, his faithful soldier. David knew that his only opportunity to hide his sin from man was for Uriah to go home to Bathsheba. However, Uriah was a faithful soldier. He simply refused to enjoy the comforts of being with his wife while his fellow soldiers were enduring the hardness of battle. Uriah instead chose to sleep at the door of the king’s house. This loyalty caused David to reevaluate his devious plan and escalate the consequences. He decided to order Uriah to the hottest part of the battle insuring certain death. It was not just the enemy that killed Uriah, but also his loyalty to an unfaithful man!
