Shades of meaning
Innocent, in the full sense, signifies not tainted with sin; not having done wrong or violated legal or moral precept or duty; as, an innocent babe. Innocent is a negative word, expressing less than righteous, upright, or virtuous, which imply knowledge of good and evil, with free choice of the good. A little child or a lamb is innocent; a tried and faithful man is righteous, upright, virtuous. Immaculate, pure, and sinless may be used either of one who has never known the possibility of evil or of one who has perfectly and triumphantly resisted it. Innocent is used of inanimate substances in the sense of harmless; as, an innocent remedy, that is, one not dangerous, even if not helpful. Innocent, in a specific case, signifies free from the guilt of a particular act, even tho the total character may be very evil; as, the thief was found to be innocent of the murder. See candid; pure.
