Second that.
The point of game isn't to make it a morally enlightening experience. You can make it so if you play with children, but not when you're gaming with your chummers.
The point of a game is to have fun. If a player or GM isn't having it, it is a GM's fault.
True, I could care less what the character does IC if they are playing their character (not to be confused with being a jackass and pawning it off as such). My last group leaned towards the sociopath end of the spectrum, and that is fine. All I tell them is that there will be reprocussions for their actions. This is not me trying to correct them, but that there are honest in-game consiquences.
Like my previous example, you accidently hose a crimelords kin, there is a good chance you made an ememy. How they deal with this will determine if the problem is solved or made worse...and also gives ME as the GM more fodder for said adventure.
