if I could give them back just ten minutes of their lives, most of them wouldn’t be here.

He's wrong about that. He would need to give them back 10 minutes of their lives, and then keep on giving them back different 10 minutes on a very regular basis.

I disagree. Let's take drivers who got into a serious accident : if you "gave them just back ten minutes" so that they avoided getting into that accident, most of them wouldn't have had another accident later on. It's not as if the world neatly divided into safe drivers, who never have accidents, and unsafe drivers, who have several.

Sure, those kids that got in trouble are more likely to have problematic personalities, habits, etc. which would make it more likely to get in trouble again - but that doesn't mean more likely than not. Most drivers don't get have (serious) accidents, most kids don't get in (serious) trouble, and if you restrict yourself to the subset of those who already had it once, I agree a second problem is more likely, but not certain.
