The kindness in Caleb Copeland’s voice immediately sets himself apart from the rest of the white men Amos has met. The book implies that Caleb’s kindness sets him apart from violent enslavers, and while this may make Amos’s time in his house less painful, it doesn’t mitigate the fact that Caleb willingly enslaves Amos. Freedom and slavery are fundamentally incompatible, no matter how enlightened or kind an enslaver may be.
