Giving better than you get.

You allways have to give as good as get otherwise you're just lying there and taking it but really you should allways give better, and this works both ways:
If someone does something nice for you you should return it three fold, ten fold even because friendship should allways be rewarded,
and likewise emnity:
If some one hits you then you have to hit back even harder or else it'll just be an 'eye for an eye' sort or thing, and soon you'll both be blind, but if you hit back really hard early on then you may be able to prevent the fight from continuing and simply escalating further and further.
I suppose what i'm talking about here is 'stopping power' for instance if you use the stopping power of a knife then you'll have to stab the person alot or stab them in the heart or the neck to prevent them from coming back at you, and the chances are that person will end dead from loss of blood. It strikes me that it would be much better to use the stopping power of a gun then all you'd have to do is shoot them in the arm and then keep the gun pointed at them until some sort of help arrives, the point being to straight away escalate the fight right to its end point that way you don't get as badly harmed and and you can keep the harm to you're opponent down to a minimun.
