I've got 270+ tables of credit as a GM. No TPK's, but probably a dozen PC deaths. An uncountable number of near deaths though!
It mostly happens with unlucky timing on critical hits, or a staggeringly good roll on damage dice for spells / breath weapons.
Also a notable PC death... Channel negative energy when two players are already unconscious and within range. It was specifically stated in the tactics that one of the three anti-paladins channels negative to harm living every round... And we had a character death.
I don't enjoy killing player characters but it's going to happen occasionally. If you're rolling your dice out in the open there's no helping it. If you roll behind a GM screen, wellllllll... maybe you could fudge a bit for a party that's doing everything right, but just doesn't have luck on their side that day.
