Yeah, we see this all the time in games. Though you weren't supposed to even kill any of those guys there. It shouldn't be much of a pet-peeve anyway, unless you're playing something like Payday. It's better having them die than having the civilians/whoever stay invincible. When they put people like that in a story it can also bring in the "violence in games" issue. Fuzsion could have beat them to near-death and then execute them. That stuff is done so the player can decide if they want to kill or let someone live, there's never a punishment in between and I really don't think there should be one. Just what I think about that stuff anyway.
