What aspect of Nemesis is most notable in her mythology?

In mythology, Nemesis is primarily recognized as a symbol of justice and retribution. She represents the concept of divine retribution, ensuring that individuals receive what they deserve, particularly in terms of punishment for hubris or arrogance. This aspect of her character establishes her as a powerful force in the moral order among the gods and humans, emphasizing the belief that actions have consequences.

The portrayal of Nemesis highlights her role in balancing the scales of justice, making sure that excess, especially in human pride, does not go unchecked. This distinct characteristic is what makes her primarily associated with notions of fairness and the restoration of equilibrium in the universe, firmly placing her among the core divine figures dealing with concepts of justice rather than mercy, love, or underworld guardianship, as suggested by the other choices.
