Explanation:

Harriet Ann Jacobs' "Incidents In The Life of A Slave Girl" is an autobiographical work detailing the earlier life and suffering that slaves, especially women had to face. With the pseudonym of Linda Brent, Jacobs gave a first person narrative voice to the whole story.

The given passage is from Chapter X of the book titled "A Perilous Passage In The Slave Girl's Life" where she gives her reasons for doing what she thinks is best for herself. She drew a parallel between the women, slaves and free and their differing situational circumstances that made her do what might be considered wrong for any woman. It also shows her envy of the free women who can chose their husbands and do whatever they want. But considering her situation, she can do none of her planned ideas as she has to first make herself safe, thus ignoring what is right or wrong.
