Griffith did nothing wrong and Serpico is best boy.
I read most of the manga and I quite liked it. Definitely one of the most memorable fantasy works out there. I do think the early parts have an tryhard edgelord quality to them that I don't appreciate (you can argue with me on this but note that Miura himself said in an interview that looking back, he wasn't so sure all that sexual assault should've been there). But overall it's really, really good.
