Naruto's Betrayal: "You Thought Sasuke Was Bad?"

Naruto P.O.V

I walked through the forest, fists clenched, blood dripping from my lip, and a piercing headache that was making it harder to focus. How dare that idiot Sasuke try and talk to me about not leaving. He actually had no reason to leave... I do. I continued to walk, not paying much attention to anything that was going on around me, only stopping when I heard a rustling in the leaves that would turn out to be no more than a bird or a squirrel. My blood was boiling... and I felt my chakra reaching the surface. Control yourself Naruto... Think about the positives. Being the optimist I was, I didn't think that it would be that hard to think positively... It was. Who am I kidding? What positivity came from that village? NONE. All they ever did there was try to knock me down and hurt me... And sometimes I even let it happen. The sun was slowly setting, and crickets were beginning to chirp from various locations. This did not help the searing pain I had in my head... And neither did the boot that connected with the back of my head as I walked. I fell to the ground and clutched the now bleeding wound.
"JESUS CHRIST... WHAT THE HELL DO YOU THINK YOU're d-doing...?" My voice trailed off as I lay on the ground looking up at Rock Lee.
"NARUTO!" he screamed in his usual overexcited tone.
"I HEARD WHAT HAPPENED, AND I WAS SENT HERE BY LADY HOKAGE TO TRY AND STOP YOU... Whatever it takes." He stood above me, obviously expecting me to stand up and fight... But I simply sat there. He stood there watching me for a few moments before lowering his fists and kneeling down to my level. "Why now Naruto? After all these years... After all the stuff you let roll off of your shoulders... What was the last straw?" He had a genuine look of concern and sympathy on his face, but that didn't make what I did afterwards any less rewarding. I quickly stood up and punched Lee across the face, feeling his teeth shatter against my knuckles. "You were never the problem Bushy Brow..." He was laying on the ground unconscious as I spoke to him, blood pouring slowly out of his mouth. I picked him up and propped him up against a tree, making sure he was able to stand on his own. As he stood there, barely able to support his own weight, I removed two Kunai knives from my pack. I took his hands and placed them above his head, one on top of the other, before shoving the Kunai directly through them. Lee woke with a start and screamed in pain, only just realizing what was happening. "N-NARUTO WHAT ARE YOU DOING? AHH." I ignored him, tightly griping the Kunai in my hand. His eyes met mine for a brief moment before I stabbed the other knife into his stomach. Barely conscious anymore, he spoke to me in a whisper. "Y-You're... A m-monster Naruto... But... At least before... You could control it." I smirked. "Well maybe I'm tired of being the one who everybody steps on... Nobody bullies monsters... Unless they want to die." I turned and began to continue in the direction I was walking before. "You'd better hope the rest of the search time isn't too far behind you, because you're gonna bleed out soon."
