[EnslavedToBitterness]

I am currently looking for a few nice anime that has no high school teenagers as the main character.

Must involves...

-Main character (adult if possible) who loves to carnage humanity, or just violent or dark and straight forward most of the time...
-Lots of blood and gore and weirdness, if possible, but it is not a necessity.
-Demons... Mafia... or anything along the way...
-A little romance is okay, but not too often.
-Sad/flipped up ending... everyone dies except for a few?
-Can be sci-fi that has some dark and weird (gets you thinking) story behind it.
-Or simply... anything that's out of the ordinary... sick... pychotic... inhumane... just for freaks with nothing but pure lust for sex, violence, hate and death... =]

Anime that is similar to...

-Berserk
-BLAME!
-Ergo Proxy
-BioHunter
-Genocyber
-M.D. Geist
-North star
-Cat Soup
-and so on...

Any suggestions would be much appreciated it, thanks!
