Rejected
"Bella, that's quite enough." Voldemort said, smirking sadistically. Bella grinned and stepped back from the Muggle girl.
"Oh god, kill me…" She sobbed.
"My my my…pleading for death?" Voldemort whispered cruelly.
"Please…just kill me…please…" She whimpered. Regulus, unfortunately, was the one she looked up at with those begging eyes, full of pain and anguish. Regulus thanked the heavens that he was wearing a mask, and he closed his eyes, unable to look on. His cousin Bella was cackling gleefully. He swallowed in disgust. Now he could see why Sirius had always hated her.
"Regulus, you can do us the honour of ending her pathetic existence, no?" Voldemort asked. For a moment, the eighteen year-old froze. It has been two years since he was initiated. Sure, he went on raids, taunted the Muggles, hexed them, cursed them, Crucioed them, cut their throats open (and left before they died), but he never killed directly with the Avada before. He swallowed again.
"Of course, milord." He said in a low voice that didn't betray his panic. He stepped forward, not looking the young girl in the eyes. He raised his wand mechanically. He thought about how he would really like to kill the Dark Lord right now, and poured the emotions into the spell.
"Avada Kedavra." He whispered with no real emotion. The green beam of death struck the girl who slumped to the floor, eyes quickly glazing over.
"Well done, Regulus." The Dark Lord praised. "Dismissed." He waved his hand, and the Death Eaters lumbered away slowly, chuckling gleefully. Bellatrix walked over and placed a hand on his shoulder. He turned.
"So how was it? Your first killing curse?" She asked a bit harshly. Regulus opened his mouth, but nothing came out.
"I…I…" He gasped out. Bella sneered.
"Weak." She spat, before sauntering out. Regulus was left there shocked and dismayed. He was really regretting joining the Death Eaters now. He just didn't have the nerve and necessary evil to kill mercilessly, to torture and enjoy the pain he was causing, unlike his cousin dearest.
Regulus arrived back at Grimmauld Place and trudged up to his room.
"Master is back! Does Master need anything to eat or drink? Perhaps sheperd's pie?" Kreacher asked, taking the Death Eater cloak and mask. Regulus looked sick.
"No, it's alright, Kreacher." He croaked out. Kreacher noticed his condition.
"Is Master feeling alright?" Kreacher asked concernedly.
"I…I killed today, Kreacher." Regulus confessed, keeping the bile down, but just barely, as he thought of the torture and the curses that were used on the poor girl.
"Master killed?" Kreacher's eyes were as wide as saucers.
"Yes, Kreacher." Regulus said miserably and shamefully.
"Kreacher doesn't know what to do, Master." Kreacher said nervously.
"Just…" Regulus looked up suddenly. "Can you bring Sirius to me?" He asked. Kreacher looked puzzled.
"Does Master mean Master's no good blood-traitor brother?" He asked.
"Yes." Regulus sighed. "And don't insult him, please." He said. Kreacher bowed before disapparating with a loud crack. Regulus fell onto his bed with a defeated groan. The killing curse was merciful compared to curses such as the Sectumsempra or the Cruciatus Curse, but murdering someone in cold-blood…
"Blasted elf! What do you want, you little bugger?" Regulus heard. He sat up and saw Kreacher drag Sirius into the room. He would have laughed if not for the situation.
"Regulus? What do you want, Death Eater?" Sirius spat, drawing his wand. Regulus was hurt, but he didn't show it.
"Sirius…I can't do this." Regulus started carefully. "He just ordered me to kill an innocent Muggle girl today." Regulus said. "It was my first killing curse." He said, and he could feel the bile rising up again. He rushed to the bathroom and promptly threw up over the toilet. He heaved the remains of his previous meal out and rinsed his mouth. Kreacher followed him in anxiously.
"Is Master going to be alright? Does Kreacher need to bring any Potions for Master?" Kreacher asked. Regulus shook his head and made his way back into the room shakily. Sirius was still standing, arms folded, tapping his foot impatiently.
"Look, I know you hate everything that has to do with Death Eaters and the Dark Lord…" Regulus said.
"Too right." Sirius spat. Regulus winced. He looked up to Sirius as an idol, and wanted his older brother to be proud of him, but that was impossible now.
"I want out, but I don't know if it's a good idea." Regulus said bluntly. Sirius was taken aback.
"Of course it's a good idea, but how do I know that this isn't a trick?" Sirius asked suspiciously.
"I killed, Sirius! I'm not built for this kind of thing!" Regulus was close to having a nervous breakdown.
"Then why did you join in the first place?" Sirius sneered.
"Mum and Dad—" Regulus started.
"You could have run away like I did!" Sirius snarled, pacing. "I told you! I told you what would happen!" He shouted. Regulus cringed.
"Please, brother. Try to understand. I was under a lot of pressure after you ran away." Regulus said. "Can you help me—" Regulus clenched his teeth and clamped a hand over his left forearm. Sirius saw this and his eyes widened in alarm. "Sirius, please!" Regulus said. Sirius shook his head, staring at his brother's arm.
"No." He said, before sprinting out. Regulus screamed in anguish. Kreacher hurried forward with the robes and the mask, and Regulus donned them before apparating to his Lord's side.
