What is the importance of Moira, of The Handmaids Tale?

Moira is important to show the difficulties in the resistance movement in totalitarianism.

She is sexually uninhibited in her homosexuality in a sexually repressed society, and is punished for it. It does not stop her resistance, and she tries to escape, but is mutilated.

She escapes again, and is forced into prostitution. Yet, through it all, she does not let them beat her into submission.
