A young child tries to jump off a bridge and kill himself.
The villain, Johan Liebert, is a deeply disturbing and frightening character, being a complete psychopath who manipulates everyone around him and kills innocents in so many gruesome ways in utterly ruthless and remorseless fashion, and his eerily calm demeanor only makes him even creepier.
Rated R for disturbing violent content and behavior, bloody images, some sexuality, and nudity.
Throughout the series, many people get negatively affected by Johan's presence, which radically alters their psychological pattern towards life in a very strong manner by making them either become serial killers or commit suicide.
Near the end of the show, there is a massacre in a town that used to be peaceful. This is depicted in about 2-3 episodes, and all of them are very intense, shocking and disturbing.
Roberto is a very frightening villain, being a psychopathic murderer who gets manipulated by Johan into doing all of the actions he does in the series. His motives, and most of all behavior and actions make him an incredibly disturbing character.
The entire series is based on the idea of fear, manipulation, and human corruption. The main villain has quite a twisted mind that can be very hard to understand sometimes. The main character progressively becomes less of a hero in pursuit to kill the villain.
Around the beginning of the show some people are shot, and their children are taken into the hospital. The girl (both around age 12) is seen wandering around the hospital, whispering the word 'kill'. This could be disturbing to some.
The scenes related to an orphanage massacre can be disturbing or frightening to some.
One of the main background characters is strapped to a chair and tortured - his nails are cut past the point that they should be cut, and he is beaten. This can be very disturbing to audiences who are sensitive to torture.
Interviews with other murderers can be weird sometimes, such as one who believes he is a vampire and sucks people's blood when he kills them.
This show covers themes that are quite dark, such as child abuse, human experimentation, mass murder, torture, war, loss, insanity, revenge, and questions what the right thing is to do in situations where it may seem obvious, or where there may be no right thing to do. It is very dark and twisted.
The whole show is incredibly visceral, frightening and suspenseful, as the main villain is a psychopathic mass murderer.
