Translation of "Powerlessness" in French

The destiny of Tom and Mary ceaselessly haunted the author, weighed down by his own powerlessness to assume it.

Le destin de Tom et Mary hantait sans cesse l'auteur, accablé par sa propre impuissance à en assumer le poids.

The most serious problem the world faces is not the strength of the wicked, but the powerlessness of the good.

Le mal le plus grave dont le monde souffre n'est pas la force des méchants mais la faiblesse des bons.
