Violence for violence sake is as tasteless as titillation for titillation's sake. You can do it sure, but it's probably not going to result in anything that's meaningful or compelling. Again, I think this entire project is a huge bait and switch waiting to happen, but using a mean spirited nature as the crux of your game probably isn't going to result in something that people want to play.
Look at DOA Beach Volleyball. It is a competent minigame collection, but you don't really want to play it that much because everything is separated by giant walls of poorly animated breasts. It fails at being a minigame collection because it is predominantly more of a bad ogling simulator. If Hatred is what this trailer makes it out to be, and again, I don't think it will, this is probably frog fractions 2; this game will more than likely fail at being a twin stick shooter because it will be more of a tacky gore slide show because it feels like it needs to adhere to this "edge" that says killing people in a virtual space is enjoyable.
