Personally Responsible, National Responsibility

David offers to go to battle against his son Avshalom, but the people protest, because if he gets killed, what was the point of the war in the first place?  When Avshalom is killed, against David’s orders, he sobs and weeps over the loss of his son, even though it is his own victory and salvation.  In both cases, David evinces the tension between what he personally wants to go and do, and what the proper behavior of a king is.
