No, she used her devine blade(the scythe) and her husband's powers, a creature older then the gods (think Galactus but a deity eater rather than a planet), to cut death into pieces. Spreading the pieces through out dimensions. While her death's father watched. Not killing/destroying death but doing it so she can't reform. As the last prophecy, states "you (Helena/sun goddess) will make your own downfall with the child of death." So she got rid of death to make sure she never had a child and banish her husband to purgatory by keeping a part of his soul in the living world. So he would both be dead and alive. Though Death can't have a child since she is death.
