Tobi and Madara's moon plan... I liked it better when it was called The Matrix.
Seriously though, people die, Obito should stop being a little bitch about it. Tobi made sure many people's loved ones died in the Hidden Mist village, he killed Naruto's entire family and indirectly killed his godfather too. He helped kill Sasuke's entire family. All because one person, one friggin person, who barely noticed his existence died. His seventh grade crush more or less.... why doesn't he dye his hair, buy some skinny jeans, and go cry in the corner while cutting himself like any other emo crybaby piece of shit.
Part 1 we get an amazing villain in Orochimaru. Hell in Part 2 when we thought Pain was the mastermind, pretty badass too. I give Tobi a lot of credit for being a great schemer, intelligent as all hell, and quite the storyteller. Speaking of which, isn't uncharacteristic of Tobi not to spill the beans about his history. Everyone else he meets must be told this long winding story.... he's like the robot from Aqua Teen Hunger Force:
"Thousands of years ago before the dawn of man there lived Madara Uchiha...."
Story telling is half of what he does with his spare time, yet he's tight lipped now? Point is, I really expected him to have an intelligent, well thought out reason for this.... but nope, it's just because of Rin. As misguided as Nagato was at least you could empathize with him.
