What can you infer about IT as a character in the novel A Wrinkle in Time?

Before
Meg Murry finally confronts IT and discovers that IT is a disembodied brain that controls the
thinking of all the people on Camazotz, there are pieces of evidence that suggest IT is a
malevolent, authoritative force. When Meg, Charles, and Calvin initially arrive on the planet
Camazotz, they discover that everyone is obsessed with uniformity and lives in a perpetual state
of fear. The citizens of Camazotz also lack personality and behave like robots.

When Meg, Charles, and Calvin meet the man with red eyes, it becomes apparent that IT
is controlling his thoughts and is a manipulative, authoritative force. IT controls others by
reading their minds and hypnotizing them to share the same views. The audience can infer that IT
is obsessed with conformity and control but does not anticipate that IT is a disembodied,
pulsating brain. The audience also infers that IT is a powerful, manipulative force that desires
complete uniformity throughout the planet and represents universal evil.
