Elfen Lied, Another, Corpse Party: Tortured Souls, Deadman Wonderland, Devil Man, Higurashi When They Cry, Blood+, Parasyte: The Maxim, Hellsing Ultimate, Shiki (Also, Monster. Not brutal, but damn good)

Try Corpse Party
It's (apparently)so scary that আপনি can't sleep for days!!

Mirai Nikki/The Future Diary, Deadman Wonderland and Highschool Of The Dead.

Here's a picture of Yuno one of the main characters in Mirai Nikki/The Future Diary... Yup she's a yandere!

How about Baka and Test? There's a bloody death in almost every episode.
Okay, I'm just kidding. I would actually suggest Blood C, Mirai Nikki/The Future Diary, Attack on Titan, and Elfen Lied.

Akame Ga Kill!
