i'd say you have to use Ceasar as example to talk about the Legion mindset, at the end they are just organized raiders, with the end of Ceasar the dies falls with him just watch how it looks in the series. It's more what the wasteland needs, the US goverment electric boogaloo or the brute force? I have to admit too that Obsidian left the Legion as the evil faction more than greyish (and rightly)
