>>I have a tendency, when reading or writing fiction, to have a dark humor streak where it comes to villains getting what's coming to them.<<

Oh yes! I have such a taste for poetic justice. I love it when the villain fails, not just because of the hero's skill and persistence, but due to the natural consequences of internal flaws. One of my favorite TV shows was "The Pretender" -- partly because of Jarod's brilliant knack for hoisting each show's villain with their own petard.
