From the movie Road to Perdition (2002) starring Tom Hanks
Long story short, the main character played by Tom Hanks is a gangster who works for a rich mafiosi. He's a hitman—he kills people that the boss doesn't like. He's got a son, but the son doesn't know what his daddy really does for a living. And one day his son decides to find that out. So, basically one night he follows him out and sees how his dad and another gangster kill a man. But the dad catches him and everybody knows that his son saw what happened. The following is a short dialog between the daddy and the mafiosi:
— How is Michael? ls he okay?
— I've spoken to him. He understands.
— That's tough seeing that for the first time. Well, you turned out. You can't protect them forever. If it wasn't this, it'd be something else. Natural law.
I'm not really sure what he means by you turned out.
