Theres a few differences between GTA and movies, but to focus on a big one, in GTA you have agency over your character. In a movie, its always a 3rd person perspective of somebody else breaking laws. In games, you are the one calling the shots.

I believe most people are rational enough to separate the fictional game world from reality, but by bringing reality closer to the game, I think it’s a valid concern that it will influence those who struggle with that to behave more like their avatar in the game.

I don’t think it’s a bad idea, it would be rather cool. but there is a bit of risk associated with it.
