well yes, but from a moral stand point, i really don't want to leave someone blinded or,with a permanent disability just Coz they had a few beers , had a row with their girl friend and then decided to take it out on me, its not at all proportionate to the " crime" if i can put them off the,whole idea by bopping them on the noise, then that seems best . From a legal stand point, the less damage you do, the less heart ache and hassle you will get from the law if it comes to having to justify the,amount of force used,
its so much easier to say, he attacked me, so i gave him a punch and broke his nose, than it is to say, he attacked me, so i poked him in the eye, permanently blinding him, then smashed three ribs, broke an arm, cracked his neck leaving him in a wheel chair and then choked till he passed out and left him brain damage. Just saying!
