Ender, as an ultra-rare 3rd child in a world wide society/government that enforced a 2 child per family policy (long before people started to realize such was stark raving mad), as a "super-genius" (why a 3rd child from his parents was allowed, if not quasi-required), potentially had many more such fights, at some level recognized that, and was essentially bred to respond in such a fashion (weasel word since the authorities were rolling the dice in the hope he'd be a suitable balance of his older siblings).
Very much a special case, only partially applicable to situations in the real world, here and now.
But there's reasons the short story and the first novel resonate with so many of us....
