Alright. I have a new game idea. Cannibal Cops. The twist is that you play as one of them kinda like Stubbs the Zombie. You're initially controlled by a central intelligence agency and used to keep law and order, only at some point you break your programming and wonder if consuming villains is ok or not. In another twist, you end up thinking it IS ok and gobble someone down. The scene results in a lot of controversy online and we all discuss whether or not first person cannibalism in a game is appropriate.
Back to your regually scheduled program: I never was attracted to the GTA games for just your concerns. It always made me uncomfortable to be a bad guy in a game or shoot police. Duke Nukem's LARD pig aliens (get it. LAPD, LARD) also kind of bothered me along those same lines... um... but I still played that one.
It's an appealing fantasy to be the guy to break the rules or misbehaive. It's also great fodder for media of all sorts. Gangster movies in the 30's used to draw a lot of controversy. People thought it glorified gangsters and their lifestyle. Well, it does, but a movie is arguably not a huge influence to act out in real life. Same with games. A few people do act out, but they are very few. So some people like the bad guy fantasy, it's just not me.
