Why does antigone say Ismene will earn the loathing of the dead?

Antigone tells Ismene that she will earn the loathing of the dead because Ismene refuses to help her bury their brother Polyneices, who has been denied a proper burial by Creon. In Antigone’s view, failing to honor the dead is a profound betrayal of familial duty and respect for the gods. She believes that those who do not stand up for what is right will face the consequences, including the scorn of the deceased, who are denied the peace of a proper burial. This highlights Antigone's strong commitment to her moral beliefs and the significance of honoring the dead.
