If Cain walked into a classroom of Ables with his rock, there may have been one dead Able based on the element of surprise, but after that there would have been one dead Cain, or at the very least, one disarmed Cain. On the other hand, in Bible 2, the Return of Cain, the aforementioned Cain walks into a classroom of Ables, this time with an ArmaLite 15 with say three 30-round magazines of 5.56 NATO ammunition.

Cain maybe has a beef with the town that has so many Ables... like the Able sheriff that picked Cain up at the city limits for looking sketchy, or the Able deputy that tried to shave Cain's beard outside of the sheriff's office holding cell. Whatever the reason, Cain says Able drew first blood. And if you've seen one Able, you've seen them all, thinks Cain.

So Cain decides the classroom of Ables needs to go, and he takes them all down. Or maybe, just maybe, after 15 Ables go down in the first 26 seconds after Cain enters the classroom's only entrance, a Die Hard Able, using a dead Able as a meat shield, heroically rushes Cain and knocks Cain down and only 2 more Ables die before the remaining 8 Ables are somehow able to subdue Cain.

Seeing this, God says, "Dude, maybe I should modify commandment 3... who cares if my name is taken in vain... we apparently need a 'Though shall not mow down a crowd of people with a rapid-fire boomstick' commandment. I figured that was inherent when I authored number 6 with the 'no murder' and all... but it seems there are some seriously effed up people that should not have access to such kill spraying devices. Who knew?! Well, I guess the town of Ables are idiots for allowing such things to not be seriously regulated or outright banned in the first place."

So says the lord... amen.
