Grim and Reaper

Psychopath is a person suffering from chronic mental disorder with abnormal or violent social behavior.

Karin and Rebecca the closest of friends since birth. Everyone saw them as their facade made them, the most innocent girls alive. It was true for a while of them being innocent till one day on a cold dark night where it happened. The incident that changed their lives forever. Murder. It was then that they figured out who they were.
They didn't start out like most with killing cats and such no they headed right in, killing their very own teacher Mr. Klutch a perverted teacher who sought out no good. The screams of their very first victim didn't scare them at their young age of 11. No it did quite the opposite, it intrigued them. The blood pumping through their veins pure bliss and joy. The blood all over the room and the corpse was like their own little art piece.
