From Create Your Own Story

You walk in between the two arguing prisoners.

"What the CRAP are you doing?" you shout at them.

"What the crap do you need to know, moron?" one of the prisoners shouts back at you.

"Stop arguing. Now."

You see two white lines run right past you, then a splatter of blood.

You stare up at the watchtower behind you.

"Important lesson: They're on Death Row, bound to die anyway. You got me, Seventeen?" shouts the guard from the watchtower.

"Yeah, yeah, whatever. I don't want to kill everyone for no reason."

"What the frick do you mean 'no reason'? They're mostly on death row for killin' someone else or they're some mob leader. Gun em' down and you get reputation. That's an important lesson, Seventeen. Even if it is against the friggin' law."
