I don't see where he's directly responsible for that. People live their own lives and need to take responsibility for them. I also don't understand using every bit of minutia to discredit someone. We've all made mistakes and had hard times. But maybe that's just me.
They are good books. If I had to choose I would go with the first one. He doesn't explain why his son killed himself. I am not sure he knows why. Good books anyway. There are a few people I would like to talk to and Tony Dungy is one of them.
I'm halfway through Uncommon now and it's pretty good. He talks about how to not fall prey to a lot of things that men succumb to. It seems aimed mostly at young men at about university age, though. For older men, I think Steve Farrar's books are better.
