Gal 6:1 Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.
Before you condemn a person for losing a battle with their personal demons be sure you count your own battles and losses.
No one is exempt from such battles. Some are more obvious than others, but that does not make them any less a battle. Some who have kicked a person when they were down have been known to fall to the same demon they despised in the other person. Walk softly in grace not in condemnation.
