It's obvious that Caesar doesn’t trust Citizen, seeing him as a restless young man who will surely cause trouble. Of course, it’s true that Citizen has
already caused trouble by stealing the bucket of nails from the mill, but Caesar doesn’t know that. As such, his assumption is somewhat unfair, since it’s based on nothing but assumptions—assumptions made simply because Citizen is a young Black man. Caesar therefore perpetuates racist ideas even though he himself is Black, suggesting that he has internalized the bigotry that is so deeply ingrained in the country.
