How many of you realize that the paranoid, murderous rages of Charlie Manson are quite possibly identical to the paranoid, murderous rages of Adolph Hitler? Both were taking untold numbers of drugs during their lifetimes, from Pervitin (amphetamines) to Benzedrine to LSD and 20 to 30 other mind and thought-altering prescription and recreational drugs. Their ability to think had been compromised, yet no one looks at the smoking gun.... DRUGS and resulting brain damage.
The nine serial killers detailed in Serial Murder Syndrome, Volume II, all seem to have one thing in common: Left Temporal Lobe head injury and brain damage caused by drug toxicity.
Ed Gein - Beaten about the head by his drunk father.
Richard Speck - So much head injury his head "looked like a mountain range."
The California Vampire - Burned his brain out on drugs during the sixties. Suffered from undiagnosed Cotard Syndrome.
John Wayne Gacy - Fell out of a building onto his head at 18.
...and more.

Author Victor Godot has gone into even more critical detail in this expanded volume.
Do you really want to know what causes serial murder?
