I'm going with Zodiac. Putting sunglasses over the sack covering his head, leaving a heap of evidence, never got caught, taunting the police, all of his victims left at 57.3° radials intervals to Mt. Diablo, etc. etc.
Really mind-blowing stuff(Edited 22 seconds later.)
George W. Bush.
H. H. Holmes.
Albert Fish. An absolute monster: he said he raped/killed over a hundred children.
And the letter he sent to the mother of one of his victims... christ.

I do not support favoritism of serial killers. The most fucked up and terrible serial killer is all of them. H.H. Holmes was quite the contraption genius.

I bet the electric chair made that guy cum so hard.
Paul Bernardo and Karla Homolka.
My favorite serial killer is Anders Behring Breivik, for he is the hero that Norway needs.

He's actually a spree killer, not a serial killer.

Maybe not my favorite, but I have a personal story directly related to him. My grandfather was having heart surgery performed at Shands (The University of Florida's hospital), and my grandmother, sister, and I were staying at some shitty motel in Gainesville. In the middle of the night, we were awakened by sirens and flashing lights everywhere. It wasn't until a couple of days later we found out that one of his victims had been discovered about 50 yards away from our motel room. True story.

Hmmm...
Well, at least now I know there is a difference.

Interesting right? Then you also have mass murderers, like those Columbine chaps.

imagine fucking seeing this at night

I also really like Gary Heidnick.
Criminal career
1976: First legal charges
In 1976, Heidnik was charged with aggravated assault and carrying an unlicensed pistol after shooting the tenant of a house he offered for rent, grazing his face.
1978: First imprisonment
Heidnik signed his girlfriend Anjeanette Davidson's sister, Alberta, out of a mental institution on day leave and kept her prisoner in a locked storage room in his basement in 1978. After she was found and returned to the hospital, examination revealed that she had been raped and sodomized and that she had contracted gonorrhea. Heidnik was arrested and charged with kidnapping, rape, unlawful restraint, false imprisonment, involuntary deviant sexual intercourse, and interfering with the custody of a committed person.
The case went to trial in November 1978; he was found guilty and sentenced to 3 to 7 years in jail.[1] The original sentence was overturned on appeal, and Heidnik spent 3 years of his incarceration in mental institutions prior to being released in April 1983 under the supervision of a state sanctioned mental health program. In 1980, Heidnik gave a note to a guard stating that Satan shoved a cookie down his throat that prevented him from talking. He was silent for the next 2 years and 3 months.[2]
[edit]1986: Spousal rape
After his wife Betty left him in 1986, Heidnik was arrested yet again and charged with assault, indecent assault, spousal rape and involuntary deviant sexual intercourse. The charges were later dismissed when Betty failed to appear for the preliminary hearing.
1986-1987: Serial rape and murder
On November 25, 1986, Heidnik abducted his first random victim, Josefina Rivera. By January 1987, he had five women held captive in the basement of his house at 3520 North Marshall Street in Philadelphia. The captives, who were all African-American,[8] were sexually abused, beaten, and tortured. Heidnik would torture and sexually abuse the women individually or in groups. He dug a four-foot-deep pit that he used as a form of isolation punishment. After placing a captive in the pit, he would then cover the pit with plywood and heavy weights. The victims were encouraged to inform on each other in return for better treatment. Heidnik also frequently forced the women to beat each other.
One of the women, Sandra Lindsay, died of a combination of starvation, excessive torture, and an untreated fever. Heidnik dismembered her body but had a problem dealing with the arms and legs, so he put them in a freezer and marked them "dog food." He cooked her ribs in an oven and boiled her head in a pot on the stove. Police came to the house due to the complaints of a bad odor, but left the premises after Heidnik's explanation: “I’m cooking a roast. I fell asleep and it burnt.â€[9][10]
Heidnik used electric shock as a form of torture. At one point, he forced two of his captives, bound in chains, into the pit. Heidnik ordered Josefina Rivera and another woman to fill the hole with water and then forced Rivera to help him apply electrical current from a stripped extension cord to the women's chains. Deborah Dudley was fatally electrocuted, and Heidnik disposed of her body in the New Jersey Pine Barrens.[11]

Most serial killers are not cannibals.
