Not really a big problem, but I just wanted to ask around if those who have DMing experience have ever felt bad that a PC bit it.

In my current game, we have an adorable little rogue who is a bit of a chicken in combat but an excellent con artist. Her strength really sucks, and since our adventure has been loads of combat, she's been doing quite badly. (She did fatally crit sneak a hobgoblin wizard once, though). In today's session she unwisely waded into melee at 8 HP. A hobgoblin fighter used Power Attack on her and chopped her down to -9. She's definitely not going to die since the cleric was right behind her---still, I found myself wishing for the first time that this character wouldn't die. Anyone ever felt this way?
