Obito's actions and choices are understandable. Even though they were wrong you can't completely blame him. Obito is Naruto, except Naruto had the will to never give in. Plus, Uchiha have the Curse of Hatred
Obito<<< Watching the war between Obito and Naruto's team and I swear I've cried at least five times throughout the whole thing. Feels, feels, and feels again with a touch of nostalgia over the entire Naruto series.
