Children who kill their parents often fall into one of three categories, as outlined by Dr. Kathleen Heide: those suffering from severe mental illness, those with psychopathic traits and antisocial behavior, and those who have been horrendously abused by their parents. The first group experiences psychotic episodes, leading to extreme violence, while the second group kills as a manifestation of psychopathy. The third group, often the most tragic, kills to escape prolonged abuse. In cases like Anthony Templet’s, featured in the Netflix documentary I Just Killed My Dad, forensic evaluations reveal the impact of severe abuse and neglect, offering critical insight into their actions and defense.
