Re: Twelve Reasons I Love Star Trek Into Darkness
Kirk beating him was absolutely gratuitous and him abusing his position for a personal reason (he was angry because he held Harrison responsible for killing Pike. He even said it)
This is spot-on, also I believe it is why Marcus sent Kirk after him. He hoped that Kirk's feelings for Pike would affect his judgment. Which actually fits the character, as we've seen in episodes "The Conscience of the King" and "Obsession".
