Clooney's crew hits up Terry Benedict for $ 36M or so to finance the drill, and Terry states: "I want you to double my investment and I also want you to steal his diamonds." He also states: "I don't care what you do with them, I just want him to lose what is important to him."
Now, IF Terry wanted the diamonds for himself, he could've easily said during the negotiation, "I want the diamonds." But he didn't.
So what changed his mind? Why at the end of the heist does Terry send his 'French partner in crime' to steal the diamonds on the roof top? If he wanted them, all he had to do was ask at the time of the investment.
Did I miss something or is this just a hole in the script?
