COERCION
against someone's will
without a person's consent or agreement.You cannot force me to come with you against my will!Against their will, the men were made to stand up against the wall and be searched.
of one's own accord and of one's own free will
by one's own choice, without coercion.I wish that Sally would choose to do it of her own accord.I'll have to order her to do it because she wont do it of her own free will.
