The Tailed Beasts truly deserve to be "sealed off" from shinobi as corrupt ones abuse their powers. The Five Kage have made LOTS of mistakes, which led to wars and deaths of many shinobi (Onoki in particular). I really think that the one thing that still drives Sasuke is Justice and, despite his decision leading to deaths of the Five Kage, the plan surely leads to peace (but not necessarily for an eternal one)

What did Gaara and Mei do as Kages to cause lots of deaths?
