I think the biggest problem with Katsuya is that he accidentally surrounded himself with idiots and yes men who can't think for themselves and rely in him for every little thing. Then when they finally try to be independent and like Katsuya they don't have the skills to back it up.
Ironically I think if Akira and Katsuya could get over their issues they would make a great team and compliment each other well.
Akira would be blunt and cold but would be able to keep up and keep each other's worst tendencies in check while having the skill to back up their bluster.
