Ok, so lets say you have some Gnosis 0 human whose family is murdered by a greater elemental or something (Gnosis 30-35). Having lost all he loved, he dedicates his miserable life to ki development as a method of one day brutally slaying it. Cut forward a number of years, and the human is now a level 30 ki user (tao or technician). He finds the Gnosis 30-35 creature, and finds because he's gnosis 0, he can't kill it. So thus he must destroy all of reality, emptying it into the void of oblivion, so that the laws of reality that dictate he can't kill it, no longer apply. Thus he may murder his tormentor.
...It seems that requiring everyone with a beef against a high gnosis being to destroy reality to settle the score is a bad way of building a game. Did the writers ever consider a sliding scale in which your Gnosis at least 'matched' your ability to annihilate all of existence in an angry vengeful fury? Just saying.
