Deplorable Instinct starts with the disturbed protagonist, Ethan Wright, getting into trouble at his high school Oakmont High. He fights with teachers, ditches class, showcases inappropriate envy towards female students, and is overall a dangerous nuisance. Though whenever he comes home from school, he is faced with a plethora of abusive actions at the hands of his mentally ill parents. After dealing with abuses throughout the first few chapters, Ethan takes out his frustrations by brutally murdering small animals by means of skinning them and dipping their corpses in salt. After stalking a female student named Veronica, Ethan decides to act on his worst urges and attempt to murder her with his fathers work hammer during school hours. He then goes home to an empty house, where he steals his mothers Prius before the infamous dog scene plays out. Eventually, this behavior leads to Ethan meeting another antisocial boy named Angel. Angel and Ethan find out they have a lot in common, and start to partake in antisocial behavior together. Together they also enjoy listening to extreme music such as "Mayhem - Freezing Moon". 
For example, they go into the forest and using power tools start causing extreme physical harm to the homeless population nearby, mutilating them to near death. Eventually however this friendship is interrupted by Ethan's abusive family, who is always on his case. After partaking in violent and murderous behavior throughout the book, Ethan is eventually confronted by the FBI as well as mental health professionals. Though he manages to escape them through clever manipulation tactics, and goes back to his murderous ways immediately. 
After a severely negative event with Ethan's parents takes place once more, Ethan decides he can no longer take their abuse and decides to murder them by means of arson. After committing this heinous act, he steals their firearms and goes to Oakmont High School to finish what he had started. He violently murders several students and staff members, before police officers swarm the building in an attempt to neutralize him. After a lengthy chase throughout the campus, Ethan is eventually cornered and decides the only way out is through suicide. However after attempting to shoot himself through the roof of his mouth, he finds himself waking up in an ambulance, unable to speak due to the bullet devastating his entire jaw, which is now covered in sutures. After struggling to get out of the gurney, Ethan surrenders himself to his ungodly fate as he sees the school campus fade out into the distance. 
After this, a short segment titled "Epilogue" plays out, where an ignorant newscaster from Denver7 starts making assumptions about why Ethan did what he did, angering his victims who are being interviewed.
