Deceit is a recurring idea in Slim's life. Growing up, Mama uses deceit to betray both Henry Upshaw and Slim's biological father for revenge. Perhaps this early demonstration of betrayal influences Slim to deceive and trick people in his own life. Certainly, his family's choices have a strong influence on the life Slim leads and the deceit his mother shows Henry Upshaw early on could set the stage for the own betrayals Slim engages in.
