In what ways does Ismene differ from her sister, Antigone, in Antigone

Ismene is very different from Antigone. She is quiet, soft spoken, and completely subservient to the authority figures around her. She does as she's told, even if she knows it's wrong, simply because she has been told to do so. Ismene is obedient and believes men to be superior. She does, however, attempt to take responsibility for Polyneices' burial in order to die alongside her sister, even though she had no part in the burial and tried to talk her sister out of it.
