You have a point but lots of people have affairs and one night stands and don't consider the consequences for their families , or don't expect to get caught, and they wouldn't get this kind of treatment as a result. This wasn't even really an affair, probably way more low level than that in a lot of ways (unless they were of an illegal age). No idea why he sent photos of himself identifying who he was mind.
I know someone who slotted a 19 year old intern from work just the other month while his wife was pregnant, same age as me (early 40s), apart from some guilt he's faced zero consequences from it so far, both professionally and personally. Whilst wholly condemnable, I don't think he should be driven to suicide over it, which could be the risk for some of these more high profile cases.
He has obviously let himself down and there will be consequences but I don't feel outraged by it, folk make mistakes. In fact, I'm bored of the story now (though admittedly I reopened this thread out of choice).
His TV career is toast, the rest is his business now.
