Based on the Hero Archetype, I think the mistake Merlin made was agreeing to release the Great Dragon in Season 1 and then in Season 2 repeating that mistake in fighting Sigan. Kilgharrah and Aithusa might represent the Twin dragons of dependency representing the safety of the past and unknown fears of the future in the Hero's Journey which can prevent Merlin from accomplishing the true goal of his quest: the creation of Albion where magic is tolerated. For Stage 5 and beyond, Merlin must steer a safe course in the present so that he can carve out his own future. That doesn't mean that Aithusa is evil; it means that Aithusa might have some incentive to push Merlin in one path while Kilgharrah has an incentive to push Merlin down another path to establish the promised land of Albion.
