So you think it would be a good thing for the game if, say, everyone always full-looted/sac'd. Yeah. I don't think so.

Yes, it can be a learning experience to have all your gear destroyed and have to rebuild from the ground up.

It can also be a learning and character building experience to, say, have your spouse murdered. Does that mean we should congratulate the murderer for doing the person a favor?

Besides, the looting/sac'ing isnt' the only reason he's an ass. It's just part of the package.
