Smallville, Season 5

Lex:
Dr. Litvack told me the odds of survival I had going into surgery. Pretty reckless roll of the dice, don't you think?

Lionel:
On the contrary, son. What I did may appear callous, but opting for my son to have surgery was a deliberate decision.

Lex:
But it wasn't your decision to make, was it? You went against the doctors' advice not because you wanted to save me, but because you couldn't bear having a cripple for a son.

Lionel:
You may hate me for taking the risk, but I had to make a choice. And you're alive, and you can walk. I had to give you that chance.

Lex:
And what if I hadn't made it? How would you have justified your decision then? How dare you play God with my life.
