@Kirito. I would still go for Sharingan though, both in the Ninja world and the real world, it's just that cool and useful.

Orochimaru had eyes on Uchiha and Itachi long before he even started his nasty experiments, if I'm right. He was onsessed with the Uchiha power, and then started to try to be immortal.

I don't know if edo Kimi is filler or not, but CM power is enhanced by Edo temsei, as the sound Four proved.

Though Kimimaru was near illness, this manga really focuses on the poin of will power and the will to protect someone making one stronger and such, not saying that it made him stronger, but Kimi's will to help Oro made him fight ignoring his health.
