There are game that punish you for killing. In the first Fallout you could kill kids but the only thing you gain from that is a "perk" that decreses some of your stats and can make people attack you. In GTA the polis get's after you and in Deus Ex your brother and the dude in the armory gets pissed at you if you just go in and kill everybody.
