Mosiah explains why the removal of a bad king typically leads to the shedding of blood. Such a king protects himself, surrounding himself not only with guards, but with those who benefit from the king’s policies. The king then enacts laws that promote his particular ways of deviating from Jehovah’s social laws.
Mosiah had declared in verse 14 that he had led his people to peace, and here indicates that the opposite of his righteous rule would be a king who led his people into war. The result of this series of arguments is that “it is not expedient that such abominations should come upon you.” The solution will be a change in the way that the Nephite government operated.
