YMMV / The Young Poisoner's Handbook

• Complete Monster: Graham Young is a psychopathic teenager determined to become the greatest serial poisoner in history. First poisoning one of his friends and trying to do the same to a girl he has a crush on, Graham decided to kill his stepmother merely because she harshly disciplined him, systematically poisoning her until all of her hair fell out and she was rendered paralyzed, as well as blinding his sister by spiking her eye drops to prevent her from finding out what he's doing. Finishing his stepmother, Graham then did the same to every single member of his family and nearly everyone on his street before being caught. Apprehended and placed in a mental institution, Graham manipulated a doctor into granting him an early release, and drove his only friend to suicide by passing his traumatic memories off as his own in order to fool the doctor. Getting a job at a photography equipment manufacturer, Graham began poisoning all of his coworkers just for minor annoyances, killing two and injuring dozens more, before revealing that he will eventually try to kill all of them in one go in his bid to be remembered for eternity.
