Death Eater
Draco, as well as Dudley Dursley, was indoctrinated with his parents' beliefs. Rowling commented that "The moment Draco got what he thought he wanted, to become a Death Eater, and given a mission by Lord Voldemort, as he did in "Harry Potter and the Half-Blood Prince", reality finally hit him" because his dream was "so very different". Rowling also stated that there was a real moral cowardice in Draco, but that he was not wholly bad.
