No it does not. Keep in mind that your goal in self-defense is to keep yourself safe. You are not an action hero so do not act like one – that’s the truth about martial arts.
Most people make the mistake of staying and “getting some more action.” Maybe it is their pride or maybe there is too much adrenaline in their system. Whatever you do leave the first chance you get.
Once you are safe, do not go looking for more trouble. Call the police and let them handle the situation.
Heroes usually end up in cemeteries. You do not want to be part of that gang.
