They did cut a lot out to make the villains just be villains though.
In the manga, both Jamil and Fatima had a short explanation of why they became so twisted.
They were still evil, but did give some light into why they had become what they were.
Both of these tidbits were omitted from the anime, most likely for pacing issues, but probably also to simplify the villains.
But Ryosai never got these treatment.
The warmonger was just a prick and a bastard. No SOB STORY attached.
