The best korean drama villains

Nobody thought Dong Ha from Suspicious Partner was really great? I was mesmerized.
.
I second SWDBS The guy from Strong Woman was pretty creepy. Good acting, though. 

Mishil (Go Hyunjung) from Queen Seon Deok
Chae Do Woo (Kim Kang Woo) from A Man's Story
YooJin (Song Yoona) from The K2
Taejoon (Yoo Jitae) from The Good Wife
Kim Bonggoo (Yoon Jemoon) from King 2 Heart
Shunji (park kiwoong) from Bridal Mask
Minjung (Lee Yuri) from jang bori is here
Dad/Killer (Kim Uinsung) from W: 2 worlds
Sung Hoon (Yang sejong) from Duel
Gwi (Lee Soo Hyuk) from Scholar Who Walks the Night
Taejoon (Jo JaeHyun) from Punch
Kwon Jae-hee (Nam Goong Min) from The Girl Who Sees Smells
jin pyo (Kim snagjoong) from city hunter
Seokhoon (yoon junghoon) from Mask
sooyoung (Joo soohyang) from school 2015: who are you

Mo Tae Goo from Voice (Kim Jae Wook was really brilliant in this), one of my fav villains ever

Cho Gab Soo from Witch's Court

Spiritual Father from Save Me

the evil twin in Defendant (got the names mixed up xD)

Nam Gyu Man from Remember: War of the Son 

1. Cha Moon Sook (Lawless Lawyer)- I LOVE a smart villain and the way she manipulated Bong Sang Pil, the ML, had me rooting for her
2. Yoon Hui Jae (Come and Hug Me)- straight crazy but wonderfully acted
3. Oh Jae Uk (The Five)- another smart villain steps ahead of the protagonist

and a special shout out to Lee Joon- he seems to always be playing the bad guy/ creep in whatever I watch with him

Yeon Minjung (Lee Yoori) - Jang Bori is Here
When watching this I thought that this girl will win Daesang, and she really won it :D

Jung Woong In - I Hear Your Voice

Uhm Ki Joon -  Defendant
