I just wrote this a while back as a challenge to turn the protagonist of any work of fiction into an antagonist. Very short piece but I hope you enjoy it! :)
Harry gritted his teeth and squeezed his eyes closed, trying to stop his fingers from reaching for the wand in his pocket. But it was so close... So tempting. Before he could make any rash decisions he threw himself onto the bed and wrenched the velvet curtains closed around him. From outside, he heard Seamus mutter, "What a headcase." Something snapped in the scarred boys head at that moment. Within a second he was pointing his wand at the gap in the drapes, the torture incantation clawing up his throat. He relished the screams of agony that echoed around the small dormitory. He could see the white, horror-struck faces of his class mates surrounding their agonised friend, but he ignored them. There would no doubt be other disbelievers around the castle, but he held power over them all.
