damn, i dunno which side to take on this argument. good storytelling
I'd say Beyond is in the right here considering it was shown that not all of the Demon King's army was evil and some, like the dragon clan, were coerced into joining.
Plus, Raagar has nowhere to stand with his argument since he never cared about what the Demon King was doing or did to people. Hell, he was just about to slice up the audience just to anger Beyond, the guy's a sociopath.
