Equiano’s story would have been useful for abolitionists as his journey on the slave trade ships was (and still is to this day) a devastating account of mistreatment and the horrors that many Africans faced.

I would say isolation because Elie and his father are separated from his mother and 2 sisters so that he and his father go to the forced labour camp and his mother and sisters go to the gas chambers though the mother and one sister survive he does not see them again, at least not there. And seeing his father become helpless so that he must become his father's caregiver makes him resentful and then ashamed of his resentment.
