Great insights, so nothing much to add, except for one. :)

I'd say that although Garen sees Darius as a butcher, Darius is a hero and valiant general of Noxus in his own eyes, fighting for his nation and its beliefs.

Vladimir, in his Judgement, after a few false answers, reveals he essentially fights because he enjoys killing, especially after claiming to fight for the glory of his homeland.

I think Darius knows or suspects this, and despises Vladimir for being a Noxian without their particular form of principles: martial honour, patriotism, strength of arm. Vladimir probably WOULD find Darius to be a wasteful brute without finnesse, too grim to delight in the pain and suffering he spreads.

Also, I doubt Talon murdered Quinn's brother. I think it's more like the 'relationship' between Garen and Katarina: Two contrasting yet well-matched warriors clash and form a recurring rivalry.

Personal pet theories: Sivir is rediscovering a heritage of somekind and a new identity, perhaps providing Nasus with another soul to guide after years or even centuries of isolation. And Renekton, fallen after unleashing his rage and power, finds Xerath to be the one being to sort of maybe identify with his plight. Or it could be an alliance of convenience.

Addendum: While I'm not going to overly commit to or deny whatever lore the official page suggests, it's always fun to analyse. XD
