Answer:
Ismene differs from Antigone by being weak and submissive.
Step-by-step explanation:
Unlike Antigone, Ismeneia was submissive and cowardly (to the king and the men), not having the courage to honor her family and help her sister. If we look at the angle of enforcing law and not morality, Ismeneia would be right, because if each one used his own morals, there would be no justice.
