The ones you think capture that sense of desperately craving to butcher people who have severely wronged you in the past. i'm not a vengeful person but i do find some of these highly rousing and intense.. a few of my favorites:
-3 inches of blood - destroy the orcs (totally over the top and almost laughably cheesy but it captures the intensity pretty well)
-sentenced - vengeance is mine (the lyrical content is pretty much spot-on, "i have dreams of hammering your skulls, fantasies of bashing in your brains, obsessively, i am watching, i am stalking"
-judas priest - screaming for vengeance (again, pretty over the top but it's all about the intensity, the SCREEAAAM)
