symphonic poem ''forbidden prelude'' (Drakengard 2), I mean... its not so mutch murder evil, but its definetly twisted.

Most compositions from Drakengard 1 give the mood that your being stalked.

Graveyard from WoW.... judge for youself.

the ambient music from Devil May Cry (1.2.3.), all have that evil intent that gives you a chill.
