Did the btk killer have mental issues?

The BTK killer, Dennis Rader, exhibited behaviors that suggest he had significant psychological issues, including a need for control and a compulsion to kill. Some experts have speculated about possible personality disorders, such as antisocial personality disorder or narcissistic personality disorder, given his manipulative behavior and lack of empathy. However, Rader himself denied any mental illness during his trial, claiming he was simply "a normal person." Ultimately, while he displayed disturbing traits, a formal psychological evaluation would be necessary to diagnose any specific mental issues.
