Not at all the same. I will not, under any circumstances, do something I think will cause real harm to someone in a sparring match. That takes away weapons like kicks to knees, etc. If I'm attacked, I do not mind causing damage.Fighting is self-defense. You have to fight against bad guys to defend yourself. When your fist meet on your opponent's face, he will no longer bother you any more. It's better for your fist to meet on your opponent's face than for your opponent's fist to meet on your face. Self-defense doesn't mean that you don't fight back. You do fight back and that's "fight" by definition. Of course you can run, but when someone attacks your family members, you just can't run away and you have to "fight".
