Dark themes dramas

I'm looking for more dark themed dramas to watch like really dark themed. My faves that I've seen (or am watching) so far are:

• Alice in Borderland
• Girl from nowhere
• A gift to the people you hate
• Erased
• Extracurricular
• Death Note

So more stuff like any of those. 

Not scary though, just dark. Like murder and betrayal dark.

Thank you! ^^
