Answer:
The question is centered around the novel "Uncle's Tom Cabin" written by Harriet Beecher Stowe,
Explanation:
The Fugitive Slave Act of 1850 was the motivation behind the writing of the novel.
The author means that slave-owners become essentially a despot, without Christian love. Thus, for Stowe slave-owners were in essence evil-beings without compassion and ethics. Thus, the blame of slavery was in the South, in the plantations owners, her reasoning being the beforementioned lack of Christian love.
Therefore Stowe uses Christianity as a way to portrait the misery of slavery but also as a way to give a way to challenge it. For Stowe, her background as the daughter of church leaders heavily influenced her view, influencing her view and her arguments, based on the Christian doctrine, against slavery. Basically, that slavery would end only through a purge, a necessary purge through Christian love and compassion, basicaly of an atonement by the American society.
