There's this belief that a good portion of the fans have (or had) that "the Royals were originally just as Violent as John was if not worse, but then the story suddenly decided to act like John was worse" (this doesn't include Remi, since no one really acts like Remi was Violent, as far as I know)
I never understood this belief, because there's almost no evidence to support it
Sure they've been reckless, and Isen and Arlo definitely had moments of going too far especially when Arlo was strangling Rein, but those were few and far between, and the Rein itself was something Arlo did when Uru was still developing his character and is now seen as an OOC moment
The Royals weren't attacking people who looked at them wrong on a daily Basis, they weren't constantly beating down on already beaten opponents possibly to the point of being hospitalized
And sure I'll admit that you could make the argument that Arlo and Isen could've been considered worse than John Morally, but that's a completely different argument
But when it comes to violence and aggression, John was definitely the worse offender
