Seconding
Parasyte The Maxim (Kiseijuu: Sei no Kakuritsu). Not a demon though (alien), but most certainly in the "omg powah - do not want!" category.

Tokyo Ghoul is this turned up to 11, and with something more akin to demonic magic. Also, episode 12 just has one of the most fucked-up anti-altruism messages of all time, though the second season starts to drag a bit.

Both are over the top violent as fuck though. Blood, blood everywhere.

He doesn't really seem to mind all that much though.

Not like Parasyte and Tokyo Ghoul where the MC's main theme is all, "OMFG GET THIS OUT OF ME!!!"

Sounds like Devilman is right up your alley. However I've only read the manga so far. The manga was great, but I've heard the anime adaptation is quite different and not nearly as good. I believe there were some OVAs made which adapted it more closely, but I haven't seen those either.

Here's a link to a dubbed version of the OVA so you can see what I'm talking about: https://www.youtube.com/watch?v=OEf3b7RY90E
