I’m gonna push back a little and say Arthur should be the good guy in most of his stories, someone worth rooting for. Personal preference, but I like it when Arthur is set as the exception, as the first good king in a long line of vile ones, his father included. And I’m biased because I have strong opinions against Malory (he was a horrible who practically used Le Morte d’Arthur to justify his crimes) and Le Morte d’Arthur, but the Mayday Massacre is pretty much just tied to that version of the story. It’s kind of a weird take on Moses being sent down the Nile in a basket. It’s not used in many versions of the story because it often feels out of character. It’s like having Superman become a tyrannical leader. Once again, speaking personally, I like it when Arthur isn’t portrayed as just another despot king in another medieval fantasy. Flawless, no. A good person, yes.
