One of the fundamental assumptions that has been with DnD since the beginning is that the heroes break in to these underground vaults, murder the occupants, and take their stuff. People break these assumptions all the time. But the whole practice of stealing from the dead is immensely common. It even spreads outside of DnD/Pathfinder when DnD/Pathfinder players play games that aren't set in a psuedo-medival fantasy world.
Try pointing this out at your pathfinder game and see all the groans when you insist the party not steal from the dead. You don't see it quite as much in other games, like the new and old world of darkness with the possible exception of DnD immigrants or if they are looking for something specific. My Vampire probably isn't going to rip up his enemies apartment looking to pawn his laptop and guns (which would probably be a terrible idea anyway.) Why is this idea so persistent in a game supposedly about heroes? You don't see the heroes, or even most anti-heroes in other media stripping their fallen foes of all of their possessions to sell.
