Despite his ruthless personal ambition, Aramis is an extremely loyal friend: in fact, his only mistakes come when he refuses to harm or offend his friends. In "Twenty Years After", he follows Athos's pleas to spare the life of the villain Mordaunt, and in "Le Vicomte De Bragelonne", he refuses to suppress d'Artagnan's discovery of the truth about Belle-Île-en-Mer. Aramis even tells his friend Porthos the true identity of the Man in the Iron Mask, despite fearing that this will lead Porthos to kill him (Aramis). Friendship is so important to Aramis that, at the end of "Le Vicomte De Bragelonne", it is strongly implied that he cries - for the first and only time in his life - after causing the death of one of his friends.
