Orwell’s stint in a Trotskyist battalion in the Spanish Civil War—during which he first began plans for a critique of totalitarian communism—influenced his relatively positive portrayal of Snowball. As a parallel for Leon Trotsky, Snowball emerges as a fervent ideologue who throws himself heart and soul into the attempt to spread Animalism worldwide and to improve Animal Farm’s infrastructure. His idealism, however, leads to his downfall. Relying only on the force of his own logic and rhetorical skill to gain his influence, he proves no match for Napoleon’s show of brute force.
Although Orwell depicts Snowball in a relatively appealing light, he refrains from idealizing his character, making sure to endow him with certain moral flaws. For example, Snowball basically accepts the superiority of the pigs over the rest of the animals. Moreover, his fervent, single-minded enthusiasm for grand projects such as the windmill might have erupted into full-blown megalomaniac despotism had he not been chased from Animal Farm. Indeed, Orwell suggests that we cannot eliminate government corruption by electing principled individuals to roles of power; he reminds us throughout the novella that it is power itself that corrupts.
