That was it. That was the final straw.
I stood there, everything going by as if they were in slow motion, watching the spell aimed by me hit the curse made by him and repel back and go toward him instead of me.
Then the terror spread across his face and he realized he was going to die. The curse hit him and he fell, spread eagle on the floor. Then the moment after the confirmation was made that he was truly dead, the Great Hall erupted into ear-shattering screams of joy. People were hugging others and tears came down from faces, and lovers were kissing madly. I, however, stood there in disbelief, soaking every second of this in. My feelings were mixed, still not exactly sure about how to react.
One part of me, though considerably smaller than the other part, was taunting, "You're a killer now, Harry, no greater than Voldemort. You should of let him suffer, let him not go on to the great beyond." The other part was arguing, "We defeated him, and now the world is free of his reign! Why aren't you rejoicing?" I was so caught between the two, I was immune to everyone around me, celebrating the defeat and running up to congratulate me. I couldn't see how happy everyone was, partying at the end of his reign and waiting to start their new lives. The sides arguing were drowned out by a new, more powerful voice, saying, "Every beginning comes from some other beginning's end" The second side's voice suddenly became more powerful and more insightful, winning the argument between them. I snapped back into the world around me, smiling at all my friends and celebrating with them.
