Garra from part one is essentially the most mentally unstable character to grace the manga. He killed people and yearned to bathe in their blood just to feel alive as he put it. If anyone puts Sasuke over it, you need to stop over-loading your head with coke. It does stuff to you. Also, I am flabbergasted Karin is not included. That ***** killed hundreds of prisoners and threw them in mass graves all because of their longing for freedom. I am glad Sasuke showed her no pity.
