Saint
Antonin held his wand in a death grip as he circled Auror Alexei Bulgakov. All the senses of his body were strained and alert, even his skin seemed to tingle and itch with the expectation of an attack.
"Always knew you'd end up a miscreant, Dolohov," Bulgakov jibed. "Just like your Slytherin cronies."
Antonin snorted. "Do all Gryffindor's become self-righteous, obnoxious aurors, or are you an exception?"
Bulgakov bristled. "Gryffindors are defenders! Gryffindors are brave and valiant and righteous and—"
"Exceptional brash, thoughtless, stupid, and sanctimonious."
Bulgakov scoffed. "Everyone has faults, but compared to a Slytherin anyone's a saint!"
Sinner
The Auror and Death Eater continued their circling, the tips of their wants sparking with constrained magic.
"You speak of ideals, Bulgakov, yet you betray your own pure blood. You speak of ideas and yet your department is infested with corruption. Your kind are only too willing to torture children for information."
"Outrageous!"
"It was auror who tortured my sister to death! She was fifteen. And it was the auror-controlled Wizengomot that put me in Azkaban for defending her!"
"Enough!"
Bulgakov threw the first curse – an Encearo. Antonin deflected it – "We're all sinners. Accept it" – and answered with a Crucio.
Savior
When Tom Riddle first founded The Organization it was not only legal but immediately summoned large amounts of support from pureblood families, even those that would later fight on the opposing side once the war began. The Rosiers and the Mulcibers were proud to see their heirs rise through the ranks. Lucius Malfoy was a prominent ally. Tallis, Lestrange, Nott, Black, Goyle, Bullstrode, Lawrence, Yaxley, Parkinson. Even Litman, James, and Pruett who later switched sides… the lines of support grew exponentially. Many purebloods saw Riddle as a savior, the organization as a chance. There was no end to their enthusiasm.
Killer
Walden McNair didn't know why but somehow he always ended up as the brutal executioner. In school he was one of the larger boys in his year and therefore was typically manipulated by friends into beating up some annoying Gryffindor. His father had introduced him to muggle weapons, such as axes, which Walden developed an interest in, despite his mother's horror. During Voldemort's reign he was often sent out to do the dirtier, "hands-on" work that the likes of Malfoy shirked. Killing had become such an everyday thing that the already somewhat brutish Walden became more than accustomed to it.
Martyr
Regulus Black had always been an idealist. Fed pureblood dogma from a young age, Regulus had joined Voldemort with the utmost enthusiasm, seeking to prove himself to be worthy of his name and blood. Yet, Regulus didn't have the stomach to be a Death Eater. His very first raid was a miserable disaster. When Regulus turned on Voldemort he knew he would die but he was willing to face death, willing to suffer because he was doing so for a cause. A different one, albeit, but that didn't matter. IN the end he got to play the hero, the martyr.
