This is the true heart of looting. Emotional grief. Yes, most of us think the way Dirty does when we die, but it's the opportunity to find those diamonds in the rough, those overly attached and emotional pixel-huggers, that drives us to kill those that do not want to be killed.
PvP'ers are generally a differet breed than sheep. I think Roby and Moxie are talking the sheep, not the PvP'ers. With the PvP'ers we get challenge and the fun of beating a skilled opponent. With sheep we get access to torment the souls of the weak. Both are enjoyable, and I want my games to give me access to both.
