depiction of slave holders ( men and women) in the Incidents
Although he is based on Harriet Jacobs’s real-life master, Dr. Flint often seems more like a melodramatic villain than a real man. He is morally bankrupt and lacks any redeeming qualities. He is thoroughly one-dimensional, totally corrupted by the power that the slave system grants him. He sees no reason not to use and abuse his slaves in any way he chooses, and he never shows any signs of sympathy for them or remorse for his crimes. If Dr. Flint expresses kindness, it is invariably a ruse to try to get Linda to sleep with him. Dr. Flint represents the cruelty, callousness, and treachery of the entire slave system.
Dr. Flint loves power above all else, and it often seems that forcing Linda to submit to him is more important to him than simply sleeping with her. He is galled and infuriated by her defiance, and he becomes obsessed with the idea of breaking her will. Rather than simply raping her, he persists in his efforts make her acknowledge his mastery. When Linda escapes, he pursues her relentlessly, putting himself hundreds of dollars in debt to chase her to New York. After his death, his venom and determination seem to be reincarnated in the form of his son-in-law, Mr. Dodge. Dr. Flint neither changes nor grows over the course of the narrative. His malice, representing all of the evils of slavery, appears to affect Linda even from beyond the grave.

As far as Mrs. Flint;
Linda’s mistress and Dr. Flint’s jealous wife. Mrs. Flint is characterized mainly by her hypocrisy. She is a church woman who supposedly suffers from weak nerves, but she treats her slaves with callousness and brutality. Mrs. Flint demonstrates how the slave system has distorted the character of southern women.
