You think that's killer? I've slaughtered more player characters in one session than all of you here put together in your entire lives. It was to the point where I had programmed a "character-o-matic" to spit out characters at the drop of a hat. My current kill record is 89 characters in 3 hours. It got to the point where stats weren't even rolled unless you survived your first adventure. Hell, I'm the one responsible for 4 out of the 10 entries for "You know your DM is too hard": #1, #5, #9, and #10.
It's amazing how high the body count can get when you simply have your human-intelligence monsters apply actual military tactics to their attacks and ambushes, and use personal experiences in the Vietnam War as a source of inspiration for adventures. Parties of level 10 characters have fallen prey to a handful of standard kobolds with crossbows and punjisticks.
