moral·ly adv.

Synonyms: moral, ethical, virtuous, righteous

Ethical stresses idealistic standards of right and wrong: "Ours is a world of nuclear giants and ethical infants" (Omar Bradley).
Virtuous implies moral excellence and loftiness of character: "The life of the nation is secure only while the nation is honest, truthful, and virtuous" (Frederick Douglass).
Righteous emphasizes moral uprightness; when it is applied to actions, reactions, or impulses, it often implies justifiable outrage: "It was righteous anger that motivated letters written by whistle-blowing employees" (Sandra P. Thomas).
