'Sheep' represents the unthinking, conforming masses of society who blindly follow orders, are easily manipulated, and eventually resort to violence when pushed too far.
The 'Sheep' are the largest group, symbolizing the general populace who are content to follow the rules, remain oblivious to their exploitation, and accept their lot. Lines such as 'Harmlessly passing your time in the grassland away / Only dimly aware of a certain unease in the air' perfectly illustrate their complacency and ignorance. They are led by the 'Dogs' and controlled by the 'Pigs,' existing in a state of naive contentment until their collective suffering reaches a breaking point. The song's climax, where the 'Sheep' finally rise up, 'scattered out on the highway, screaming for revenge,' shows a dangerous shift from passive obedience to violent rebellion. This transformation highlights the potential for the oppressed to become just as destructive as their oppressors once pushed beyond endurance, but also suggests their rebellion is ultimately uncoordinated and perhaps futile against the entrenched power of the 'Pigs.' It’s a chilling portrayal of mob mentality and the consequences of systemic oppression.
