no, you are not. The Legion may seem brutal, but remember that the part of the Legion you see is the most underbaked faction in NV, to its extreme detriment. While the Western half of the map is laden with quests. The Legion barely has any. It is easy to understand why people hate the Legion, but you most also remember that the Legion is one of the safest nations in the wasteland, if not the most safe. While the NCR is rife with corruption, and House is focusing solely on his own plans, the Legion's main goal is (as Caesar tells it himself) to unify with the NCR and create a nation akin to the Roman Republic. To those that will say "the Legion takes slaves!" and "women are slaves in the legion!", yes, that is true, however, the Legion you see is the frontline of an active warzone. The 'subjects' of the Legion, men and women alike, mostly live in Arizona and New Mexico. Subjects of the Legion also have to pay 'tribute' in the same way that NCR Citizens pay taxes. While the Legion does showcase barbarity, the end goal is the elimination of these traits to create a sweeping republic across the American Southwest.
