Why did Fagin said' You won't be -too-violent Bill' in Oliver Twist film?

In the film adaptation of "Oliver Twist," Fagin's line "You won't be too violent, Bill" reflects his manipulative nature and his attempt to control Bill Sikes, a violent character. Fagin recognizes Sikes' propensity for brutality but tries to downplay the intensity of his actions, perhaps to maintain a sense of loyalty or to keep Sikes from going too far and jeopardizing their criminal enterprise. This moment underscores Fagin's pragmatic approach to his relationships with his gang members, prioritizing their utility over their morality.
