How was squealer to blame for the breakdown of anamalism?

Squealer played a pivotal role in the breakdown of Animalism by manipulating language and distorting the truth to serve the interests of the ruling pigs. His persuasive rhetoric convinced the other animals to accept increasingly unjust policies and betray their original ideals. By continuously altering the commandments and spreading Propaganda, Squealer undermined the principles of equality and solidarity that Animalism was founded upon, ultimately leading to the farm's descent into tyranny.
