I think he said it very well when he referred to "he felt entitled..."
Pure and simple.
And, we don't need a million dollar pyschiatrist to figure that out or some Dr. on a talk show who has an over inflated salary to tell us that.
He is not now, nor will he be, the only athlete /celebrity / politician, etc. who's felt "entitled."
The "deep rooted psychological problems" are simply what the "average person" would say - "I thought I could get away with it."
