Just throwing this out there but it's a really bad idea to assume someone's thought process and feelings based on one photo taken. We don't know what he is thinking or feeling and I think it does no good and doesn't contribute to the discussion about Mariah's case by speculating on someone else's feelings. For all you know he broke down in tears (he didn't, just saying) the moment after this photo was taken. Of course he looks smug here, that's what the photog was going for, they don't take pictures to record things, they look for shock factor and what they know is going to upset people.
IMO, I think it's a waste of time and mental energy to keep rehashing what we think he is thinking or feeling, to speculate on his looks because ultimately it doesn't matter. He could be falling on the ground in despair and lamentation and empathic psychics would still say "Oh..look at him..he doesn't care, he's upset for himself...hang him...HANG HIM!!!" We should be focusing on finding the truth, not Earl's mental state.
Just my 2-cents.
