Prosecutor Paul Fairley said: "Why, given your account that you were frightened and thought that you were being assaulted, why did you seem so eager to get back into the fray and engage Mr Kent?"
He replied: "Because he was persisting to get back up and continue the fight.
"I guess at that point I was pretty angry and I wanted to make sure that he stops fighting me."
Sidney Chan, pictured in a club, is accused of kicking Stephen Kent.
Fairley said: "You had completely lost your head, that fact that the member of your group was having to lift you forcefully off the ground to get you to move in the direction that everyone else was moving."
CCTV footage shows Kent seen falling to the floor, but the view of his body is obscured by a parked car as Chan runs by him twice.
