It is scary to think of such things as moral boundries being less than hard edged, but this is the way it is.
One of my favorite actors, Hal Holbrook, started young with extensive makeup and did very creditable performances as Mark Twain who travelled widely and performed solo for audiences. In one of his monologues from Huckleberry Finn, Huck finds himself in a moral quandary, because Jim is running away from his legal owner. Huck lies to the slave hunters and feel guilty about it, but he reflects on the fact that if he'd turned Jim in he'd feel bad:

"What's the use you learning to do right when it's troublesome to do right and ain't no trouble to do wrong, and the wages is just the same?"
