Nagato Uzumaki: I have my Ideals, and will fight for them. I also belive the ends justyfy the means...
Itachi Uchiha: I'm a quite calm person that rarely looses his zen... I don't care about other people's oppinion about me, as long as I know I do what I think is right...
Danzo Shimura: Same as with Nagato... I'm a Machiavelist, and would do whatever I found necesery for the greater good.
Orochimaru: I put science & research before ethics... U_U and, btw, no, I'm no rapist XD!
... Yeah, I'm a bunch of badass people, xd
