And my point with the koto is that yes it only had one shot, but instead of planting the crow in naruto, itachi could have used it against sasuke during their final battle if he was truly worried about the truth getting out. Koto was last used when sasuke was like 5, and he was now 16, which means over ten years passed. the eye recharged, or it wouldn't have worked when itachi used it on himself. But again, plot. Sasuke couldnt be redeemed like that, kishimoto had plans to let sasuke get his vengenance and still fight naruto at the end. That couldn't happen if koto was successfully used on sasuke. Itachi wanted Sasuke to triumph over him; Itachi wanted to be killed for what he did to the clan, and he wanted a clan member to do it. That's why he didn't use Koto on Sasuke.

The reason the crow was implanted in Naruto was a failsafe just in case Sasuke turned down a darker path. If Sasuke took Itachi's eyes to make himself stronger, and then used those eyes against Naruto, Koto would activate against Itachi's eyes (now in Sasuke's EMS).
