Final answer:
Equiano's narrative, which includes the story of a white man being beaten to death, reveals the cruelty of the slave trade and highlights the author's personal struggle and advocacy for abolition.
Step-by-step explanation:
The story of a white man being beaten to death included in Equiano's narrative is a testament to the brutality and complex moral circumstances surrounding the history of slavery. Olaudah Equiano, in his autobiography 'The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, the African: Written by Himself', provides a first-hand account of his experiences as an enslaved person and his observations of the cruelty and inhumanity of the transatlantic slave trade. Equiano's story is a critical historical document that sheds light on the abject horrors of slavery and the struggle for freedom and human dignity.
