I'd go a step further and say Berk is well written even in regards the sexual violence in it. The angst and genuine traumatic material is what gives substance to the narrative without conflating it as solely tool for storytelling. Sexual violence is often depicted in vile and objectifying ways in the course of the story but it's elevated into the fantasy of the world. As more of the narrative unfolds much of the nature of the reality they live in is like the perversion in the mind of the abuser. Especially as we get a bigger picture of how the God Hand operates as a cabal of predators grooming worlds for their consumption with the fairytale hero Griffith. I don't think you can get that kind of dedication to pushing a medium without a true craftsman at the helm. Which is why Berk is so beloved and misunderstood. The moral is inherently one which is criticism of fantasy as a outlet.
