I voted too, but I think it's hard to explain your play-style through a poll like that.
It all depends on which kind of game I'm actually playing.
If I'm GM'ing the official quests vs. 4 heroes I'm as hardcore as it gets. The lines are drawn and I'm the 5th player, trying to win. The wizard entered the room? All monsters target him.
If playing the official quests vs. less than 4 heroes, I still try to win but also cut the heroes a little slack.
Maybe the monsters spread their attacks out over several heroes instead of ganking. But seeing a 1 BP wizard? Well, then I'll still try to finish him off.
The orcs will never go "aaaaawww".
And finally if I'm GM'ing my own quests... It's a little unfair if you want to kill heroes chaotic-style AND you design the quest yourself!
When I make quests I usually go more for story and/or puzzles. Anyone who played my quest "The Mirror Maze" should know it's not exactly a death trap.
I mean, I'll definitely try to kill the players with the tools I've given myself, but as I want to see the story unfold and the puzzles solved I take on the more traditional role of a gamemaster.
Here I don't mind just taking the players along for a ride.
