Violence is a very ugly thing. Violence is often so casual on film and made to look so cool and so sexy but violence is a repulsive repugnant act that human beings inflict on each other. It shouldn't seem to be cool and sexy ever really.
To injure an opponent is to injure yourself. To control aggression without inflicting injury is the Art of Peace.
Well it's very dangerous to project but it's clear that the existing technology has some more years to go.
