Every kill felt like another accomplished vengeance, a small satisfaction, an ephemary taste of justice that goes away as fast as it comes, leaving him empty again and again and again. Young and naive, he could never get enough of it, massacres, destruction, watching the world burn had become a need. Now grown up and mature, Obito may have stopped killing people without purpose, he hasn't changed one bit. Sometimes, he finds himself wondering; is his heart empty, or is it full of hate? If it's full of just hate, does it count as empty? Either way, Obito sees himself as a tool at this point, a tool to end this world.
Create a new one, filled with love and happiness. One where not even the concept of war exists.
Because this current world always take everything from him, from everyone. Hoping for better days won't do anything, hope is merely an illusion here, it's not real, it's just an empty dream for the futur.
But.
What he's doing right now, fighting for peace, for a better world. What is driving him to it, is that some kind of hope? And these happy pictures from happier days, holding him together and keeping him going, is that some kind of nostagia?
No….
This small tinge he feels in his heart when he looks at Minato's son fighting on the battlefield alongside the alliance, never giving up, having the whole world support him and bright dreams for the futur, is that some kind of regrets? And that decision he made to not stab Kakashi on critical organs to let him a chance to live, was it out of fondness?
NO!
He's not supposed to feel, he is but a tool! He can't fail, he can't accept it, he'll never acknowledge this.
He will never acknowledge this.
