What were David's sins?

King David committed many sins with just one situation. He lusted after Bathsheba when he saw her naked on her rooftop - she was taking a bath. He had sex with her and she became pregnant. When King David found out, he attempted to cover it up by having Bathsheba's husband, Uriah, come home and lay with Bathsheba. However, Uriah refused, so King David sent Uriah to the front lines of the war and he was killed. King David was guilty of lust, adultery, and murder.
