That is fine but makes Akito sound very paranoid. Could have Hark overly rough someone up maybe... someone picks on Hark and he goes all Ruthless but Akito only sees Hark cutting into his oppenant and assumes him as the bad guy.
Or what about Akito's been playing this video game where cyborgs take over the world. So when he sees Hark's mechanical arm his first reaction is to kick Hark on the back.
