There are few games that do this for a reason, though; it's an ineffective mode of transmitting those feelings. To do that you'd need a heavy narrative focus (whether you want to admit that or not) and the acuity to KNOW the answer, or at least your interpretation of the answer. Then you need the actual emotional maturity to simulate those ideas.
This game doesn't seem to do that, and that seems to be by developer's intent. It has one goal in mind; kill everyone. Jam your gun in that woman's face and pull the trigger, because you had a bad day at work. Listening to her beg is how you get your jollies off, right?
And at the end of the day, from a purely game-ist viewpoint, THAT'S why it's going to be a piece of shit. Killing random civilians might be fun to some people (not me) in GTA, but that's more because of the arcadey feel of the game; you have a fucking rocket launcher and you're doing crazy shit, and in 5 minutes the National Guard will come out. It's so stupid and ridiculous that people can have fun with it, even if I think those people are way too easily entertained. SR 2-4 have the same feel; Postal had the same feel, even Postal 1, which was 'darker.' If this game is attempting to avoid those tropes, and instead becomes 'shoot people because you had a bad day in a gritty, realistic world,' it's effectively shooting fish in a barrel. They can't fight back; they're powerless civilians. The worst you'll probably face is a SWAT team, and even that will probably be after you kill a pretty obnoxious number of people.
If you can have fun shooting fish in a barrel, by all means. Have at it. I can't.
