is that the PC's, which can be seen as adventurers, attract the attention of the gods. The gods recognize the potential within the adventurer and finds him interesting enough to restore him, though even a god cannot fully restore a person as he was before (which results in the 1/3 con).

Now, with regular people, citizens, farmers, craftsmen, ..., they don't attract that kind attention, so their deaths are permanent. But, they are not even remotely as likely to die as an adventurer is. Unless he's unlucky and catches a disease or meets anything else that leads to his demise.

So it depends on the mob, if you kill a farmer, he will be dead permanently (he was killed by one of those ruffians hanging around the Fortress), where an Acolyte devoted to Zurcon would be important enough to the gods to be resurrected. As would be the Svirfneblin King.

Also, a PC isn't resurrected after delete delete, because he no longer is interesting to the Gods.
