I'm a sadist in games. Call of Duty: World at War makes a good example, especially the shotguns and the PTRS-41 sniper rifle. I would aim for their legs and arms on purpose, just for their reactions. But then again, they're nazis so it's eady to say that "they deserve it" I guess.
Also, I don't care if they're female. If they're (going to be) shooting at me, they gotta expect a few dozen more bullets back their way.
Maybe there's something fundamentally wrong with me, maybe I just got the whole "reality VS game"-barrier properly in check, I dunno.
