what makes Madara so good........u talk of him as if he is my sensei........in that case u r wrong I am a current student of CaptainKenpachi......but make to the question its self.........Madara isn't one to go around and start fights........He goes around and makes FRIENDS (unlike the anbu), He does not wish to take over NB (unlike the Anbu), and just like shodaime at times but Madara shows it alittle more CAN BE TRUSTED (unlike the Anbu)
Why fight ur Leader? I see the point in sparring but not fighting him.
Now Tell Me why did u Join Anbu? the Real reason not the business line BS.
