When I picture Eve crying out her dead son's name, beating her chest and weeping, right after a chapter where her husband brings a curse of death on himself and all flesh, I see something: Maybe God's redemptive plan involves restoring Eve for her husband's doom, and restoring Eve for the loss of her son.
The unwritten message about Eve is that she is really the one who lost everything. But perhaps God will make all things right, and God will make all things new.
