Okay... somehow I managed to get to "Accepted" with the Legion. Was it by "destroying" the Securitron Bunker at the Fort while suppressing my trigger finger? Anyhoo, despite slaughtering the Cottonwood Cove garrison, I'm "Merciful Thug". How many of the savages do I have to kill to go over to "Villified"?

Well killing Caesar and the rest of The Fort should do it and not far from cottonwood is
fallout.wikia.com/wiki/Techatticup_Mine that should have enough legion to get vilified.
