Saw V2008

[Flashback]'

Hoffman:
You're assuming this is going to play out the way you want it to.

John:
I assume nothing. I anticipate the possibilities and... I let the game play out.

Hoffman:
Then why do you need Amanda in the game?

John:
To ensure that the rules are followed. She won't make decisions for anyone. She will just... offer choices.

Hoffman:
That leaves a lot to chance.

John:
If you're good at anticipating the human mind... it leaves nothing to chance.
