It's not his fault - he's always fought in wars he's had some kind of chance of winning before this; it's good strategic instinct to keep looking for an angle of survival! Or at least an angle of minimal damage. And he's fought both Cloud and an assortment of Keyblade Masters to at least a draw before; nobody ever told him that Princesses of Heart were even worse. :3
