I've found that with most "foes" there's nothing personal ... just me or them. Though wiping the smiirk off of a Thalmor face is oddly satisfying.
But I really enjoy kiliing Falmer. I truly destest the blind little freaks ... and their little Chorus' too ... and would really enjoy a "kill every Falmer in Skyrim" quest.
Is this unusual? Should I seek professional help?
