Well, I've had the idea for some kind of leader that would be opposed to the Jedi since before the casting call was released but that character description did motivate me to develop him a bit more. In the backstory I've created for the character he was a rebel who was captured early in the war and was a prisoner of war for the remainder of the conflict. So he suffered first hand under the rule of a Force user and it has warped his view on them all. This is why I wouldn't have him be a secret Force user because the very essence of his character is the complete opposite of that. He's terrified of another Force user or users hiding themselves in the government and that's the reason why he's such a zealot.
