What is the central idea of the text from The Narrative of the Life of Frederick Douglass, an American salve?

In the Narrative, Douglass shows slaveholding to be damaging not only to the slaves themselves, but to slave owners as well. The corrupt and irresponsible power that slave owners enjoy over their slaves has a detrimental effect on the slave owners' own moral health.

Explanation:

normally working animals are domesticated and ruled by a master, a domesticator (tamer), to perform basic and important functions on a farm, for example. the value used in this context is animal labor in exchange for food. it is not so much a contrast to the story told by napoleon and the pigs, since the animals of that particular farm also performed functions on the farm through domestication. the only thing is that in this case, who rules them is a pig, also an animal, but very respected, to whom the other animals lent him submission. that's about a strong relationship of dependency between animal and owner.
