The Early Life of Robert Alton Harris
Robert Alton Harris had a troubled childhood, deeply influenced by his family's issues with alcoholism and abuse. Born prematurely due to violence between his parents, he suffered severe emotional neglect, with his mother refusing to touch him and even physically harming him when he tried to connect. This neglect led to a series of traumatic experiences, including rape while in a juvenile detention facility, which contributed to his eventual criminal behavior. The discussion brings into question how much of Harris's violent actions were predestined by these interconnected circumstances and how much can be attributed to inherent evil.
