Each of the excerpts has a negative outlook towards slavery and discusses its horrors. In Passage A, Douglass laments that there was no pleasure in his condition. Whitman in Passage B describes a runaway slave he encountered; he was in poor condition when he first found him, and he was uncomfortable in all his interactions with Whitman. In Passage C, the speaker promises to get Jim out of slavery because he knows it is awful. Each of the authors is anti-slavery, and their writings have anti-slavery themes. I hope this answer can help you.
