At this level of the "Professional" avaition industry a lot of trust is put in us being honest about ourselves and our own integrity, if you're not, whatever you are attempting to hide will ususally come back to haunt you big style.
In the UK, if this particular individual had been honest in the first place, he probably would have been given recourse to some form of help or counselling.
For whatever reason he chose his own way, he's now paying the price for his lack of integrity and will find it very difficult to get back into the profession.
