DISCLAIMER: none of this is mine
Peter – There are good people; like most of the order and there are bad people like most of the Death Eaters and then there are people like me, and while I won't pretend that I'm a good person I'm not a bad person either; I just want to survive and at the time of the war surviving meant becoming a Death Eater. To survive you must please the people with power like the Dark Lord, so I did; I joined Him and when he said jump I jumped and when my friends said jump I ducked because I am a coward, doing whatever I can to stay alive. They say I'm a bad person but I'm not I'm just a coward. Just a square peg trying to fit in a hexagonal hole.
