Hey guys, but have you noticed that Tobi actually didin't kill anyone or maybe I just do not remember that, but still he could suck everybody into his dimension. At the kage meeting he did that to Sasuke and Karin easily. He could have taken all the kages. And look what happened when he declared war. All countries united and everybody is working together. I think he created war, so everybody would unite. And when he dies he might say smth like "I succeeded" It's not that hard to believe that he is actually good. He had many chances to kill Naruto and Kakashi and others, though he did not.
I think he is like evil/good.
