Is this what you're looking for?

If you like prints then look up "the Divine Comedy" and Dore.

I found some by Jusepe de Ribera

Stuff like this. Apparently this is Spanish artwork from the early 17th century.

I also enjoyed this one by Hendrick Goltzius

I didn't know if Hieronymus Bosch would be what your looking for but he was ahead of his time.

Some more famous dark artist would be:
Albrecht Durer
Francisco Goya

I'm interested in what this thread puts out since I'm bad at remembering artist names.

Caravaggio has illustrated some of the more violent episodes in the (catholic) bible, such as this painting of Judith beheading Holofernes.

This is completely off topic, but did you know there's a German death metal band called 'Rotten Seed'? Their lyrics are apparantly about violence, death and blood. Something you wanna tell us?

Perhaps demonology would be a good place to start?

This may not be christian per se but is wonderfully freaky.

Yea I did...no affiliation, I assure you.

Lann and Orthoron made excellent suggestions

Also try:

Hans Baldung (Grien), Martin Schongauer, Jacques Callot... and Michael Pacher maybe as well.
