Riven's old lore mentioned her being "on a quest to seek atonement and a way to save the pure Noxian vision in which she believed". A Rioter also mentioned in a thread from about a year ago that Riven still represents "the best of what Noxus is and could be". https://boards.na.leagueoflegends.com/en/c/story-art/6JWHilrN-rivens-faction-should-be-ionia-now?comment=0003
As far as I know, Noxus always had this "might makes right" mentality, it's why they have been trying to expand their borders since the inception of their empire and even noxian society itself follows social darwinist and meritocratic principles. Anyone who is strong and skilled enough can simply work their way up. Riven today however seems to have an entirely different set of values, with quotes like "So much death.", "A necessary strike." and "Violence to end violence." implying that her ultimate goal is peace rather than the vision of might and glory that Noxus represents. Her quote "My hands are stained." also implies that she regrets her service to Noxus rather than "just" disapproving of the chemical warfare they employed (which was NOT her fault and therefore couldn't have "stained" her hands).
So does this change in her lore imply that there is no "pure noxian vision" that she would support and that she severed her connection to the ideals of Noxus? And if not, what kind of "noxian vision" would she support?
