I think this issue will be solved only when youth culture has a massive paradigm shift and stops being fascinated by "antiheroes". Come to think of it, it's not just "youth culture". Adults display this as often as not.
At any rate, I see a larger problem with games (and the people who want them) that encourage players to do things they should not do "in real life". Differentiate that from games that encourage as player to do things they cannot do in the real world. GTA3 is a blank canvas of sorts, for the player determines whether to exploit the nonlinear freedom of the game or to exploit the "closet criminal" opportunities presented. Other games are not as ambiguous about their intentions, and those games are just fodder for the shock craving dipshits that we all know.
