You sound like a liberal. This has nothing to do with our “puritan foundations” and everything to do with someone who has acted dishonorable to himself and his family. Hell, I bet even Tiger would admit that.
Power is a corrupting influence. In Tiger’s case it came from money and the adulation of pathetic suck ups who worshiped his ability to hit a golf ball. It can happen to anyone who doesn’t have people around them to confront him/her and remind them of what honor looks like.
In the end he’s just a man with flaws and not the hero that people made him out to be. Perhaps he will find some redemption for himself in the eyes of his family.
