Name: Draco Malfoy
Age: 16
Year: 6th
House: Slytherin
Personality: Draco opts to attack his enemies through psychological warfare rather than by physical force. His elitist upbringing is often used as a weapon to belittle those less prosperous than himself, such as Ron Weasley. He also insults Hermione Granger's Muggle-born status by referring to her as a "Mudblood".He's a bigot, and he's a bully, and as I say, in the most refined sense, he knows exactly what will hurt people.

Draco, unlike Harry, never feels any remorse for his actions: Draco is someone who is very capable of compartmentalizing his life and his emotions, and always has done. So he's shut down his pity, enabling him to bully effectively. He's shut down compassion — how else would you become a Death Eater?
