I don't think Maul can be developed more. He's evil because he's evil - just look at him.
I respectfully disagree. In the EU Maul was written as unwaveringly loyal and devoted to Palpatine, that he practically loved him as a father, and IMO it didn't come off as out of character or hamfisted at all. Any PT rewriter could utilize and empathize these personality traits; Maul can be more than just a cool looking gimmick.
