Of course, both variants lead to the death of a Sim. There are two variations of this attack, with the chest stabbing being quite brutal as Sims leap at their target and violently stab them multiple times. If fists aren't enough to get the point across, then Sims can just straight up take a knife and stab others too. The Extreme Violence mod lets players violently assault and choke other Sims to the point of near death.
