Nerf Now!! 1552
It's easy to go in a murderous rampage when your victims are mostly scared unarmed teens.
But being a undead monster with a weapon isn't anything special in the Mortal Kombat universe. Hell, 1/3 of the current cast fit the description.
If anything, people would giggle at Jason crude «fatalities». Like a monkey with a brush trying to do art. No class, no finesse.. just senseless hacking.
Meanwhile people are doing sculptures with their opponents guts, with them still alive and screaming.
