Uchiha Massacre !
Well , i think that the uchiha incident has to be done so badly cuz none of them would grow up to be any good.
If there were no uchiha in the first place they wouldn't be having all these fighting and bullshit about world peace.
World peace will be achieved if the Uchiha ,all of them, including the remaining few, had been annihilated .
I mean look at the whole shinobi world fighting two members and they are Uchiha. Orochimaru knew he could change the world if he got the Sharingan, cuz he knew it was Evil ! Even Sasuke has done terrible things with his eyes, meaning u can't provoke a Uchiha cuz they will ruin ur life forever. The only guy with the Sharingan who is a non-uchiha is Kakashi and he is using it right, then why would the Uchiha use their power for evil ? Is it because they inherited Madara's hatred ? Even Itachi used his eyes to hurt a comrade , and i know he means well but still...
Anyway, A World without Uchiha = World peace. What do u think?
