The Best Top 5 Psychopathic Serial Killer K-dramas on Netflix

  1. Voice

      Voice is a South Korean tv show, it contains 3 seasons coming out to 44 episodes. Moo Jin Hyuk is a "Mad Dog" detective who becomes guilt-ridden after his wife was murdered while he was at work. Kang Kwon Joo is a tough Police Woman who is gifted with perfect super natural hearing abilities and voice profiling skills. She was working at the call center when a brutal murder case took place, killing her father and Moo Jin Hyuk's wife. Three years later, Jin Hyuk and Kwon joo team up as the "Golden Time Team", solving cases together and chasing after the serial killer who took away their loved ones. 

This drama is truly one of a kind, I absolutely in love with serial killer dramas so this was perfect for me. I'd say this is actually one of my favorites, I love the emotions from Kim Jae Wook and how he shows Psychopathic Mental Illness so well. I can guarantee your gonna be in love with this one. It is a bit Gory and Brutal , so if you can't handle stuff like that i would consider choosing a different one.

2. Bad Guys

Bad guys is an 11 episode tv show, containing 1 season. To reduce Violent Crimes the Police Chief asks Detective Oh Goo- Tak to form a team consisting of criminals, to help get rid of other criminals. Detective Oh Goo-Tak is currently suspended for using excessive force. Detective Oh Goo-Tak gathers a Gangster, A Young Serial Killer with extraordinary intelligence and a Contract Killer. Also, A Police Inspector, Yoo Mi-Young. Together they fight criminals and try to become better people while discovering themselves in the process, Not to mention every mission they complete that person gets a year sentence reduce. 

This was also one of my favorites, once again I love dramas that include serial killers. This drama has lots of plot twists and deep stories hidden. I recommend this strongly, it doesn't contain as much gore as "Voice" so that's also a plus.

3. Strangers From Hell

Strangers from Hell is a one season TV Show with 10 episodes. Yoon Jong-Woo is a man is his 20's. He has lived in a small town for half of his life, but he ended up moving to Seoul for a small office job. He moves into a very small residence with weird and suspicious residents. Turns out moving there was the worst mistake of his life. 

This was seriously the creepiest thing i've ever watched borderline. So many creepy characters and weird plot twists, But i've gotta say its super good, i couldn't stop watching when i started, even though i was freaked out heavily LOL.

4. The Guest

The guest has 1 season and 16 episodes, not super long. Crimes caused by mysterious powers take place, A psychic, a Catholic Priest and a detective fight against these crimes. Yoon Hwa-Pyung is the psychic, he was born into a shaman family. Yoon Hwa-Pyung seeks out those possessed by evil spirits and attempts to expel those evil spirits.   

Choi Yoon is the Catholic Priest, He is cynical and cool-headed. He doesn't like having relationships with others. He is recognized for his abilities as a Exorcist

Kang Kil-Young is the detective, she doesn't believe in evil spirits nor exorcism, but her views change because of Yoon Hwa-Pyung and Choi Yoon

Together they try and fight the powerful spirit "Park Ill Do".  

I didn't know if i was gonna like this one or not, but trust me it's so good. I love the emotions displayed in this one, it also has lots of plot twists which is very entertaining. I put this evil spirit one on this list because The evil spirit is literally a serial killer. This is super good, nothing to gory or gross. Well i mean kinda, but every crime drama is gonna have something brutal in it LOL.

His wife is murdered by the mass men sent from Argos. They beat Kang Ki-Beom and stabbed both of his eyeballs out.

He is selected to become a member of Rugal, a special team organized by the NIS. Through Biotechnology, he gains 2 artificial eyeballs with a special ability.

This drama was literally perfect. The plot, emotions, characters, it was all so good i couldn't stop watching. Although I do hate Chon Duk Gu which is the brutal serial killer.
