It is literally unpredictable ?

I feel like satan is that new cop but the story got twisted. Bc earlier they said he was fighting against Bael but what if that's all fake... what if he's actually working under him! Plus that woman the religiously obsessed one. I have a feeling she's the true serial killer. Like the drug-addicted guy might have killed that officer but what if he was set up! I have a feeling that the true serial killer is that woman.

The overly religious woman, is not the killer. It already revealed that she is a victim of killer J’s family member. As for who killer J is, I believe that killer J is the second son of Assemblyman Jeong when he’s high on drugs. As for Satan, I believe it’s either the oldest son or the Assemblyman himself. That family is really suspicious. 

As for the new cop, it was also revealed that he’s Paimon who works for Bael and hates Justisia. 

I think j and Satan are the same person cause i feel like the ml and fl need to be connected to smth which is why I am guessing Satan might be Kang Bitna's former father-in-law as if Satan is in a human body and j's case has been years ago, he might have grown old, also they keep showing him at least once in every episode

ORRR
There's isnt Satan and everyone just want to find an excuse to excute smth for themselves and also they may be making Satan look like the bad guy as because he did smth wrong too. 


ALL GUESSES

You're so right, literally everyone is suspicious to me.

That is a good guess. The Assemblyman’s family is super suspicious, so Satan can be anyone in that family. 

If Satan and J are 2 different person, my guess (after watching ep 11) is that Satan is the FIL and the elder brother is J. If Satan and J is the same person… then I really have no idea, maybe ep 12 will show more

live update - my guess was right :O

this is my guess too

Satan and J are the same person... He just used the younger son/brother in the recent years for dirty work by manipulation....... For the dramas timeline is more likely to be the old Assemblyman.... Because 25 years ago the son would have been kinda fcking young to start serial killing. 

Satan can switch bodies - so it can be he still is the old dude BUT after he was limited by old age he used the sons - and since he raised them they are mental

Thanks everyone for answering, I also want to know about it.
