“Well, my idea is this: we’ll rustle around and gather up whatever pickins we’ve overlooked in the state-rooms, and shove for shore and hide the truck. Then we’ll wait. Now I say it ain’t a-goin’ to be more’n two hours befo’ this wrack breaks up and washes off down the river. See? He’ll be drownded, and won’t have nobody to blame for it but his own self. I reckon that’s a considerble sight better ‘n killin’ of him. I’m unfavorable to killin’ a man as long as you can git aroun’ it; it ain’t good sense, it ain’t good morals. Ain’t I right?”

– Mark Twain

The Adventures of Huckleberry Finn, Chapter 12. One of the thieves that Huck meets on the steamship. Even robbers have a moral if hypocritical code apparently – don’t kill if you can leave him to drown.
