Better Ending:

The girl kills his father, and as he walks towards the car, Tim Roth opens the rear doors of the car looks up and smiles, before yelling "oi" In a referance to his earlier comment of telling the kid to shout "oi" instead of using his name.

Or something in which the Kid leaves with Tim Roth.

Capitalism: *beep* on the little guy whilst making him feel like he has a chance.
