Carl goes berserk, hacking for 10 points, but in his fury, he forgets to defend himself, getting punched for 6 points. Carl is at 9, and J-H is also at 9. Looks like a fair fight now.
Carl gets in the last hack, dealing 9 points of damage. J-H is at 0 HP and is destroyed! Lucky for Carl constructs are destroyed at 0 or else he would have been hit, too.
