"But the “peculiar institution,” as Southerners came to call it, like all human institutions should not be oversimplified. While there were cruel masters who maimed or even killed their slaves (although killing and maiming were against the law in every state), there were also kind and generous owners. The institution was as complex as the people involved. Though most slaves were whipped at some point in their lives, a few never felt the lash. Nor did all slaves work in the fields. Some were house servants or skilled artisans. Many may not have even been terribly unhappy with their lot, for they knew no other."
