If Sasuke is a missing nin now, shouldn't Konoha take it upon themselves to hunt him down and dispose of him? Why is it simply a matter of giving the clound ninjas permission to kill Sasuke? Do they want the secrets of the Sharingan to fall into the hands of a rival village.
If the sharingan is as great as it is, I wonder if anyone made an attempt to salvage the eyes of all those Uchiha that were massacred by Itachi. Somebody should have put in more effort into researching Sharingan transplantation, given Kakashi's success with it. A transplanted sharingan may not be as good as the real deal, but it seems alot better than no Sharingan at all.
And to think all this sort of research would be right up Orochimaru's alley.Looking back, Konoha has really let some of their most valuable assets just walk away. It does bring into question the credibility of past leaderships. I wonder how a guy like Danzou would have handled it all.
Konoha in the past seems to have been handled more like a goodwill brotherhood than a true ninja village. They are supposed to be in the military business. What matters most is getting stronger, not upholding moral values. The countries don't rely on ninja villages to teach them to be more virtuous, I believe they have temples and priests for that.
At the end of the day, they are pretty much Assassins for hire. If they dream of world peace and flowery meadows, boy did they pick the wrong profession. I wonder if ninja villages allow people with other dreams and aspirations to leave the village.
