In the Battle of Hogwarts, the Death Eaters had the upper hand. However, their savior, Harry Potter, was defeated by the Dark Lord Voldemort's killing curse and fell in front of everyone in a green light.
Draco felt his head thump and his stomach sank hard. His vision became blurry, and he could only focus on the lifeless body on the ground not far away. He couldn't control his body and ran out suddenly among the crowd who were cheering and crying silently.
"Potter!"
He saw Voldemort raising his hand holding the wand, and heard his parents calling him back in horror, but he couldn't care so much anymore. He just wanted to run to the person he had a crush on for seven years and hadn't had a chance to tell his feelings, even if he could touch him one last time——
"AvadaKedavra!"
Purpose: We should take care of even our mortal enemies.
