Harry Potter (AU) - How It Should Have Ended According to Me

Chapter 2: Dumbledore (Order Of The Phoenix)

Harry looked over at his Headmaster walking towards him. "Harry," Dumbledore said calmly but Harry knew that he certainly crossed some kind of line "please get off of Mr Malfoy and put your wand away" Harry kept his wand pointed at Lucius "Professor" Harry said to his Headmaster, tears streaming down his face "HE MURDERED RON!!!!" Harry couldn't keep his anger contained. Dumbledore looked taken aback and he looked at Lucius then at Harry again "Harry" Dumbledore said calmly "you cannot let your hate and revenge consume you. You must act within reason. Now please, get off Mr Malfoy and then we can take him to the Department of Magical Law Enforcement."
Harry looked down at Lucius and that's when he realized that he was becoming the very thing that he fought so hard to get rid of. He was becoming a killer, a Dark Wizard, a new Lord Voldemort. Harry wiped the tears from his face and slowly got off of Lucius Malfoy. The second he did Lucius grabbed his wand and Disapparated. "NO!!!" Harry screamed at the place where Lucius laid seconds before. Harry then turned to face Dumbledore, the tears returning to his eyes "This is all your fault!" Harry said. barely managing to stand. He then stumbled and fell to his knees and whispered "i'm sorry Ron..." 
Harry then burst into tears and Dumbledore walked over calmly and put his hand on Harry's shoulder. Then, Harry heard a voice inside his head "Go after him Harry..." the voice whispered "he killed Ronald.... he deserves it... find him.... and KILL HIM" 
Then, a face emerged from a trail of smoke like that of the Death Eaters. It was the face of Lord Voldemort.
 "Stay here, Harry" Dumbledore said and walked to where Lord Voldemort now stood. 
Dumbledore raised his wand "How foolish of you to come here tonight, Tom" Dumbledore said to Voldemort "The Order is on their way" Lord Voldemort looked at Dumbledore with a sense of hate "By which time I shall be gone" Lord Voldemort said as he paced around Dumbledore "And you..." Voldemort raised his wand "shall be dead" Dumbledore spun his wand and shot a hex at Voldemort who quickly deflected it. Voldemort shot a curse as did Dumbledore and they became locked, sparks flying everywhere, destroying bits of the walls and the pillars supporting the ceiling. Harry crouched and covered his head with his hands as pieces of debris flew in all directions. Voldemort moved his hand, changing the direction of his curse and trying to catch Dumbledore off guard but Dumbledore moved his hand in almost perfect unison to Voldemort, keeping their curses locked. Voldemort then stopped firing the curse and cast a flame charm and put it to his mouth to give the illusion that he was breathing fire. 
Dumbledore looked on as the fire rose in a spiral towards the ceiling of the room. But, just before the flames hit the ceiling they changed, taking the form of a serpent as Lord Voldemort laughed maniacally. The Fire Serpent moved its head quickly to attack Dumbledore but Dumbledore acted quickly and swung his wand, deflecting it. Dumbledore spun his wand as Harry tried to watch and shield himself with his hands at the same time. The Fire Serpent erupted into a wall of fire and spread out across the room, towards Voldemort. The Dark Lord swung his wand, making the flames disappear into thin air and Dumbledore took his chance.
 He moved his wand, creating a large stream of water flowing towards Lord Voldemort. The water wrapped itself around the Dark Lord, trapping him in a sphere of water. Dumbledore concentrated carefully, keeping the sphere of liquid intact and raising it slowly. Dumbledore continued to move the sphere around the room that they were in and and Voldemort stuck his hand out of the water, attempting an escape. Harry ran forward to get a better look but Dumbledore forced him back using magic. Harry stumbled and fell onto the ground and looked up once more to watch the duel between two of the greatest wizards of all time.
Dumbledore lost concentration and dropped the sphere, freeing Lord Voldemort in the process. Voldemort shouted and moved his wand up, firing a curse at the great Dumbledore, who deflected it quickly with a swift movement of his wand. Voldemort then absorbed all of the magical energy that the curse was giving off and released it with a mighty shout. The curse made its way around the room, destroying glass and leaving destruction in its way. Voldemort raised his wand once more as Harry looked on, and drew all of the broken glass shards to him and then over to use as projectiles against Dumbledore and Harry. Dumbledore raised his wand and cast a Shield Charm, making all of the glass shard projectiles disintegrate into the sand that they once were.
Voldemort sighed and looked at Harry and Dumbledore with hate flashing in his snake-like eyes before disappearing in a swirl of smoke.
