How has Casy's experience in prison enabled him to realize the necessity to build a Socialist society?

That night, Tom goes for a walk, but a deputy tells him to walk back to the cabin at the ranch. The deputy claims that if Tom is alone, the reds will get to him. While continuing on his walk, Tom finds Casy, who has been released from jail. He is with a group of men that are on strike. Casy claims that people who strive for justice always face opposition, citing Lincoln and Washington, as well as the martyrs of the French Revolution.
